In order for users to customize their profile player, I have a button that they click to update their data.  it makes a call to my app server and passes the data entities to update.

I have resorted to opening a blank window with a "your settings have been updated, you can close this now" message.

It's super ugly.... is there a better way since URLrequest methods are not allowed?

 I figured out the problem.... I'm using google app engine, and even though the crossdomain.xml file was there, i forgot to add:

- url: /crossdomain.xml
  static_files: crossdomain.xml
  upload: crossdomain.xml

to the app.yaml config file
