Excuse my bad english!
While editing reports in Eclipse, the UI is very slow. When I add a parameter, it took some seconds that the newly created parameter can be edited.
If I want to change the Checkbox field "Default Style" for a style, Eclipse hangs completely.
I have attached a Java VisualVM threaddump while Eclipse is hanging with the "Default style" problem. It seems that the thread "Thread-11" and "main" blocks on org.eclipse.gef.ui.parts.TreeViewer.
I hope you can help me soon! It's awful working with Studio at the moment.
