What steps will reproduce the problem?

After restore all text is cleared, editor is blank and disabled. I can't use it 
no more, and must close form and open it again..

I use gwt-ckeditor v0.5 integrated with Ext-GWT (GXT). Currently on windows 
platform, but error is platform independent.

Same if ckeditor is in a dialog window. Save and close the dialog, when you 
reopen, there is no text.
