Hi to all,

I've a big problem saving persistent data from javascript,
I have tested application but seem save but when I read
fields is always void

here's the function that I have already testing on my local shindig and work fine

1) if I use opensocial.IdSpec.PersonId.OWNER to write  an error message: invalid IdSpec, only viewer seems to work
    in my case Viewer and Owner it's the same people

2) I wonder if it's possible, if viewer is different peolple form owner, read data from Owner

3) Although Viewer seems work still no save data so "theData" is always undefined

Here's the sources

/**

check if a field exist the call start function

*/ 

 function testAppData()
    {  
     prnLn("checking memory ...","out1");   
     var req = opensocial.newDataRequest();   
    
     var p = new Array();          
     p[opensocial.IdSpec.Field.USER_ID] = opensocial.IdSpec.PersonId.VIEWER;   //es. OWNER       
     var idSpec = opensocial.newIdSpec(p);
    
    
     req.add(req.newFetchPersonAppDataRequest(idSpec, "MdC"), "key_data");   
     req.add(req.newFetchPersonRequest(opensocial.IdSpec.PersonId.VIEWER), "peopleID");
     req.send(handleTestAppData);     
     
    }

function handleTestAppData(data){
      
     var error=null;
     var isAlreadyInit=false;
    
     if (data.get("key_data").hadError()) {
           error = data.get("key_data").getErrorMessage();
           prnLn("Error (handleTestAppData): "+error);
                                                                       return;
     }

     if (data.get("peopleID").hadError()) {
           error = data.get("peopleID").getErrorMessage();
           prnLn("Error (handleTestAppData): "+error);
                                                                       return;
     }

    
     var peopleData = data.get("peopleID");
     var dest = peopleData.getData();
    
     var data = data.get("key_data").getData();     
     var theData = data[dest.getId()];

prnLn("ID :"+dest.getId()+"data: "+theData,"out1"); 
   
     for (i in theData)
     { 
prnLn(":" + i + ":","out1");     
      isAlreadyInit=true;
     }
    
     if(!isAlreadyInit){
    
      prnLn("please wait, initializing memory...","out1"); 
       var req = opensocial.newDataRequest();    
var JsValue = gadgets.json.stringify({"string" : "some data"});

                                                    
req.add(req.newUpdatePersonAppDataRequest( opensocial.IdSpec.PersonId.VIEWER, "MdC", JsValue),"set_data");  

       req.send(handleStoreAppId);
prnLn("please wait, initializing memory2...","out1");
        
        
     }else{
       prnLn("memory ok...","out1");
       //clearMsg("out1");
       
       start();
     }
     
         
    
    }

Hi, thanks for the feedback, I'll escalate to container team for additional info.

Hi, there are a few things issues with the code you pasted.

1. It doesn't make a difference in this case, but for the future this:

var p = new Array();

Inside testAppData should be "var p = new Object();", or "var p = {};", as those optional parameters should be associative arrays and not linear arrays like var p = new Array() or var p = [.

2. It looks like you're fetching the person data just for the user's ID to use it to access the app data response.  You don't need to make an API call to get this, we push it down for you.  To get the owner and viewer IDs, do this:

gadgets.views.getParams().ownerId

gadgets.views.getParams().viewerId

3. This will be rendered moot if you implement #2 above, but IDs are returned in 0.8 in this format: myspace.com:6221.  But the app data is keyed on just the integer part of the ID (e.g. 6221).  So when you do this: var theData = data[dest.getId()]; the getId() returns myspace.com:<user ID>, which doesn't exist inside of the data object.  So you can either strip the "myspace.com:" out of the returned ID, or use the method above to get the IDs.

Thanks,
