FriendPicker widget updated

Chris Cole — Tue, 22 Jul 2008 20:28:00 GMT

You may (or may not) have noticed the FriendPicker (MyOpenSpace.Widgets.FriendPicker) has been updated (now version 0.4). See the sample in the following app:

MyOpenSpace.Widget Samples

What does this include? A number of bug fixes. A bootstrap loader to fix IE and Safari timing issues, and more:

Bootstrapper added to main Widgets static class for loading Widgets
Support for multiple pickers on a page
Text-only mode for pickers
Keyboard support for search results
Fixed IE rendering bug of loading notice
Addition of style packs for FriendPicker

The bootstrap call looks like this:

MyOpenSpace.Widgets.Bootstrapper.createWidget("MyOpenSpace.Widgets.FriendPicker", 
	function(p){window.friendPicker = p;},
	{
		element: "pickerDivID01",
		buildSelectedUI: true
	});

Make some noise if you find issues or have suggestions.

Security changes to PostTo Send Message and Comment

Chris Cole — Tue, 06 May 2008 19:33:00 GMT

In reviewing the reactions of our user base to all the great apps being built by the community, we have been moved to give end users more configuration options in how they interact with apps. We have added a new privacy communication setting to users' profiles and slightly restricted how apps may send messages and comments. As originally deployed, an application could use the MySpace postTo extension to send messages to any user in the MySpace system, subject to that user's spam and privacy settings. To curtail abuse (occassionally a spammy app makes it thru the review gauntlet) we have tightened this up so that apps may only send messages to a viewer's friends.

Additionally, users may now disable communications from all apps (Edit Profile > Account Settings > Applications > Application Communication Settings). If an app attempts to send a message/comment to a user who has indicated they do not want communication from apps, upon confirmation of the postTo message the app viewer sees an error dialog "Undeliverable Message or Comment" and if a callback handler is attached it will receive an error response.

Intermittent timeouts for some apps

Signal Loss — Mon, 28 Apr 2008 20:45:00 GMT

Hey all, Ben from the MySpace Dveloper Platform here.

Just wanted to let everyone know that we're hearing some of you are experiencing some intermittent timeouts on apps -- eeek, that's not good!

A crack-team of engineers are on the case and I'll make updates to this blog post as I get them. Or, you can subscribe to the MySpace Developer Platform twitter account and get them pushed to you directly.

Update 4:30pm, Mon April 28: We have discovered a miss-behaving process (handling url-rewriting, of all things!) and are in the process of rolling out a fix.

Update 11:00am, Tue April 29: A patch went out last night which reduced a significant amount of the timeouts.

Application Rendering Cache Changes (Coming Soon!)

rondata@myspace — Sat, 26 Apr 2008 00:20:00 GMT

Soon we are enabling both server-side and client-side caching of the app surface content. This helps performance and creates a better user experience with those who have multiple apps installed on their profiles. Here is a quick break-down of how each type of user will be affected:

MySpace Admins & Developers will be able to:

· View their own private apps (in development, suspended, or hidden)

NOTE: Caching will not be used for these users.

All Other Users (Including Friends of Apps) will:

· Be unable to view private apps (in development, suspended, or hidden)

· No longer be able to view a private app, even if you are a friend of the app.

NOTE: Caching will be enabled for these users.

Cache time will be for one hour initially but is configurable by the team here at MySpace and all users will be able to invalidate the cache with an explicit refresh.

NOTE: The only group really affected by this change, is developers who use friends of an app to test the app, while the app is private or in development. We do have support for multiple developers coming very soon, which is intended to replace the need to use friends of an app to test while an app is private. In the meantime, private apps will only be viewable by the developer or someone with administrative rights over the application. All other users will be treated as standard users.

MyOpenSocial.Widgets - FriendPicker

Chris Cole — Fri, 25 Apr 2008 21:49:00 GMT

In the spirit of making your lives easier, we are introducing...
drum roll please...

The MyOpenSocial.Widgets library.

You may be familiar with FriendPicker from the original PostTo sample application.
Now, instead of filling your app up with tons of code cruft you can make a few simple calls for the same functionality:

//at top of file
MyOpenSpace.ClientLibraries.includeScript(
        MyOpenSpace.ClientLibraries.Scripts.MYSPACE_WIDGETS);

...
//later in a registered init
var myFriendPicker = new MyOpenSpace.Widgets.FriendPicker(
	{
	element: "pickerDiv01",
	buildSelectedUI: true
	});

...
//and when you want to see what you have
var pickedPerson = myFriendPicker.selectedFriend;

http://www.myspace.com/myopensapcewidgetsamples

This is early in development, so if you find issues leave comments here or in the forums.
Also, check back in to this app periodically for new widgets as we release them.

Container Team Updates: 04/24/2008

Donny Mack (DM) — Fri, 25 Apr 2008 03:19:00 GMT

Hello all, we rolled a few additions and updates this morning - here is a summary.

Lightweight Calls

We’ve added some lightweight calls so you don’t have to get huge extended person objects.

Note: id can be owner or viewer and the opt_params parameter is currently not used.

Indicators

[edit: proper way to access]

MyOpenSpace.DataRequest.newFetchIndicatorsRequest(id, opt_params)

Moods

[edit: proper way to access]

MyOpenSpace.DataRequest.newFetchPersonMoodRequest(id, opt_params)

Status

[edit: proper way to access]

MyOpenSpace.DataRequest.newFetchPersonStatusRequest(id, opt_params)

Note: The enums that are currently used to access the results may change, but we'll give ample notice before any change is made and will remain backwards compatible for a time before removal. example: MyOpenSpace.Group.VIEWER_STATUS

Post To

We made a few bug fixes and added callback functionality

Example Code for All

Thanks Chris!!!

var osContainer;

var dataReqObj;

var param;

function init(optResponse) {

osContainer = opensocial.Container.get();

param = {};

}

function getIndicator(stuff){

if (typeof(stuff) === 'undefined'){

dataReqObj = osContainer.newDataRequest();

dataReqObj.add(MyOpenSpace.DataRequest.newFetchIndicatorsRequest(opensocial.DataRequest.PersonId.VIEWER, param));

dataReqObj.send(getIndicator);

} else {

var result = stuff.get(MyOpenSpace.Group.VIEWER_INDICATORS).getData();

dumpProps(result);

}

function getMood(stuff) {

if (typeof(stuff) === 'undefined'){

dataReqObj = osContainer.newDataRequest();

dataReqObj.add(MyOpenSpace.DataRequest.newFetchPersonMoodRequest(opensocial.DataRequest.PersonId.VIEWER, param));

dataReqObj.send(getMood);

} else {

var result = stuff.get(MyOpenSpace.Group.VIEWER_MOOD).getData();

dumpProps(result);

}

function getStatus(stuff) {

if (typeof(stuff) === 'undefined'){

dataReqObj = osContainer.newDataRequest();

dataReqObj.add(MyOpenSpace.DataRequest.newFetchPersonStatusRequest(opensocial.DataRequest.PersonId.VIEWER, param));

dataReqObj.send(getStatus);

} else {

var result = stuff.get(MyOpenSpace.Group.VIEWER_STATUS).getData();

dumpProps(result);

}

function dumpProps(obj, parent) {

for (var i in obj) {

if (parent) { var msg = parent + "." + i + "\n" + obj[i]; } else { var msg = i + "\n" + obj[i]; }

if (!confirm(msg)) { return; }

if (typeof obj[i] == "object") {

if (parent) { dumpProps(obj[i], parent + "." + i); } else { dumpProps(obj[i], i); }

}

function postBlogCallback(){

var os_token = MyOpenSpace.MySpaceContainer.OSToken;

var message = opensocial.newMessage("I am a blog post");

message.setField(opensocial.Message.Field.TITLE, "About Testing");

message.setField(opensocial.Message.Field.TYPE, MyOpenSpace.PostTo.Targets.BLOG);

osContainer.postTo(os_token, message, null, ptCallback);

}

function ptCallback(someVal){

if (someVal == MyOpenSpace.PostTo.Result.ERROR) {

alert('callback gave error')

}

else if (someVal == MyOpenSpace.PostTo.Result.CANCELLED) {

alert('user cancelled PostTo')

}

else if (someVal == MyOpenSpace.PostTo.Result.SUCCESS) {

alert('WE ARE MEETING WITH GREAT SUCCESS!!!')

}

else {

alert('Unrecognized response: ' + someVal)

}

init();

</script>

<h1>Indicator, Mood, Status</h1>

<button onclick="postBlogCallback()">Blog post with callback</button>

Container Updates: 04/21/2008

Donny Mack (DM) — Mon, 21 Apr 2008 17:23:00 GMT

Notable Updates from Last Push

Browser Aware Resizing

    <button onclick="gadgets.window.adjustHeight();">   </button>
    <button onclick="gadgets.window.adjustHeight(0.2);">0.2</button>
    <button onclick="gadgets.window.adjustHeight(0.5);">0.5</button>
    <button onclick="gadgets.window.adjustHeight(0.8);">0.8</button>
    <button onclick="gadgets.window.adjustHeight(1);">1.0</button>
    <button onclick="gadgets.window.adjustHeight(200);">200</button>
    <button onclick="gadgets.window.adjustHeight(800);">800</button>

What they do in order:

1.    Adjust height to content
2.    Make height 20% of viewable space
3.    Make height 50% of viewable space
4.    Make height 80% of viewable space
5.    Make height 100% of viewable space
6.    Make height = 200px
7.    Make height = 800px

Delete App Data

You can now delete app data.

User Type in Person

You can now determine what a friend's user type is. Some examples are Band and Regular user
friend.getField(MyOpenSpace.Person.Field.USER_TYPE);

PostTo and Flash

We released a fix for the flash issue in PostTo

Also check out Chad's post regarding encoding urls

Encoding URLs in makeRequest

Chad Russell — Fri, 18 Apr 2008 22:21:00 GMT

Hello everybody, this is a request to everyone out there using the makeRequest function.

Inside the container we are encoding all URLs and post parameters, so please don't encode them yourselves. This will result in a double encode which will get mangled by the proxy.

If you have noticed an issue with your makeRequest function, this may be the cause.

Good:

gadgets.io.makeRequest("http://myurl.com?p=yay");

Bad (for two reasons!):

opensocial.makeRequest(encodeUriComponent("http://myurl.com?p=yay"));

The second one is bad because it: a) encodes the URL and b) uses the deprecated opensocial.makeRequest call, which is specific to OpenSocial 0.6, please update your code to be 0.7 friendly!

Thanks,

Chad

Heads Up: The non-MDP version of PostTo has been disabled

Donny Mack (DM) — Fri, 18 Apr 2008 04:07:00 GMT

I know a few of you are using the non-MDP version of PostTo found here: http://www.myspace.com/posttomyspace - I was just made aware that some issues arose today and it was just disabled until they can be addressed (which could take more than a day).They have a forum here: posttomyspace if you have questions for the team.

The MDP version is still available - please find information about it here: http://developer.myspace.com/Community/blogs/mdpjavascriptcontainer/archive/2008/04/10/introducing-post-to.aspx

Hate to be the bearer of bad news – don’t kill the messenger!

Introducing Post To

Donny Mack (DM) — Thu, 10 Apr 2008 20:14:00 GMT

In a nutshell, Post To enables you to provide your application users the ability to post things to MySpace. In our initial launch we’ll be offering the following Post To targets:

-    Posting to the viewers profile
-    Posting a bulletin
-    Posting to the viewers blog
-    Adding a comment
-    Sending a message

Each of the targets can accept different levels of text and markup. For instance, some will accept HTML while others don’t and this is sometimes controlled by the end users privacy settings. Because of this we recommend thoroughly testing your applications.

This should go without saying but, SPAM will not be tolerated!

Overview

Post To is one of our first features that will enable you to not only help your users communicate with friends but also to start virally spreading news of your application. With just a few lines of code you can start pushing content to your users profile and friends.

Post To works by allowing you to pass a few parameters to a JavaScript function that then displays an overlay over your application (see screenshots below) . The user can then perform different actions based on the target invoked and then submit or cancel the action.

Finally, Post To is currently only available on Canvas pages.

Invoking Post To

Below we’ll go through the basics of using Post To starting with a working out of the box code example. For information on things not covered please see the http://developer.myspace.com/community/myspace/referenceIntro.aspx

Sample Code

var os_token = MyOpenSpace.MySpaceContainer.OSToken;
var osContainer = opensocial.Container.get();

// gets all supported post to targets
var supported = osContainer.getMySpaceEnvironment().getSupportedPostToTargets();
var recipientPerson;

// need a person object for add comment and send message

function init() {

dataReqObj = osContainer.newDataRequest();

dataReqObj.add(osContainer.newFetchPersonRequest(opensocial.DataRequest.PersonId.OWNER));

dataReqObj.send(ownerResponse);

}

function ownerResponse(data) {

recipientPerson = data.get(opensocial.DataRequest.PersonId.OWNER).getData();

loadSupportedTargets();

}

function loadSupportedTargets() {

var temp = "<select id=\"supportedTargets\">";

for (var i = 0; i < supported.length; i++)

{

temp += "<option value=\"" + supported[ i ] + "\">" + supported[ i ] + "</option>";

}

temp += "</select>";

document.getElementById("selectInsert").innerHTML = temp;

}

function invokePostTo(){

var target_is_supported = false;

var target = document.getElementById("supportedTargets").options[document.getElementById("supportedTargets").selectedIndex].value;

var subject = "subject text";

var content = "content text";

// make sure that the selected target is enabled

for (var i = 0; i < supported.length; i++) {

if (supported[ i ] === target) {

target_is_supported = true;

break;

}

if (target_is_supported) {

// create a new message object passing in the content to be posted and then set the subject and target fields

var message = opensocial.newMessage(content);

message.setField(opensocial.Message.Field.TITLE, subject);

message.setField(opensocial.Message.Field.TYPE, target);

// show post to

osContainer.postTo(os_token, message, recipientPerson);

}

init();

</script>

<br>

postTo

opensocial.Container.get().postTo(os_token, message, opt_person, opt_callback);

os_token: The token string, this gets passed up so we can verify who's sending the request.
Message: an opensocial.Message object. The content to be posted, the message type refers to the target of the post.
opt_person: an opensocial.Person object. An optional opensocial.Person object, used when a recipient is required, e.g. when posting a comment, this person will get the comment.
opt_callback: Callback function, right now just for success/fail. - not yet implemented.

openSocial.Message

Below is the function for creating a new opensocial.Message object:

var message = opensocial.newMessage(body, opt_params);

The Post To opensocial.Message message allows for three fields:

1. opensocial.Message.Field.TYPE

A supported PostTo target type from MyOpenSpace.PostTo.Targets enum. You can check if a particular target is supported by invoking: opensocial.Container.get().getMySpaceEnvironment().getSupportedPostToTargets()
Currently supported targets:
-    MyOpenSpace.PostTo.Targets.PROFILE
-    MyOpenSpace.PostTo.Targets.SEND_MESSAGE
-    MyOpenSpace.PostTo.Targets.COMMENTS
-    MyOpenSpace.PostTo.Targets.BULLETINS
-    MyOpenSpace.PostTo.Targets.BLOG

Example:
message.setField(opensocial.Message.Field.Type, MyOpenSpace.PostTo.Targets.PROFILE);

2. opensocial.Message.Field.TITLE

A title for the post – this is not used in every target

Example:

message.setField(opensocial.Message.Field.TITLE, “Hello World”);

3. opensocial.Message.Field.BODY

The content you want to post.

Example:

message.setField(opensocial.Message.Field.BODY, “Hello World”);

Note: Body can also be passed in the constructor.
