[news.eclipse.platform] Re: [DataBinding] AssertionFailedException: "nul

[Matthew Hall <matthall@xxxxxxxxxxxxxxxxx>]

Wrap you app's main() instructions in a call to:

The default realm is set using a call to Realm.runWithDefault(Realm, 
Runnable).  The default realm is set while the runnable is running, and 
is set to the previous realm after the runnable completes.

Most of my apps have a main method that looks like this:

Display display = new Display();
Realm.runWithDefault(SWTObservables.getRealm(display), new Runnable() {
  public void run() {
    // create and open main application window
  }
});
