[news.eclipse.platform] cannot be cast to org.eclipse.ui.ide.FileStoreEd

["Andrey Ilinykh" <ailinykh@xxxxxxxxx>]

Hi there!
I have plugin written for 3.2. Now I try to run with 3.3, when I save my 
editor context I get exception.
My EditorInput implements only IEditorInput. What is the problem?

java.lang.ClassCastException: ira.editors.EditorInput cannot be cast to
