Could not evaluate javascript response:

I've tried to reproduce it with the Workbench Demo and -Dorg.eclipse.rwt.enableUITests=true in the launch configuration, but without success. Could you provide a snippet or steps to reproduce it with Workbench Demo?

kilin, any additional information/snippet on this?

Sorry ,I can not provide additional information，I think some problems in my code

From the stack trace I've extracted this snippet:
....
var wm = org.eclipse.swt.WidgetManager.getInstance();
....
wm.dispose( "remarks" );
....
var w = wm.findWidgetById( "remarks" );
w.setTabIndex( 35 );
....
It shows that somehow you try to set the tabIndex on a widget with id "remarks" after you already dispose it. It's interesting to investigate it.

kilin, what kind of widget is this "remarks" - Shell, Composite? Is this id "remarks" static, or you dynamically assign it in runtime?

Comment 7 Ivan Furnadjiev

Or maybe you assign the same id "remarks" to more than one widget??!!
