Bug 22325

Description Peter Burka 2002-08-09 15:47:39 EDT

If you attempt to use the GotoLineAction for a text editor nested inside of a 
MultiPageEditorPart, or some other nesting editor, the attached 
ClassCastException occurs.

It looks like the GotoLineAction assumes that its editor is a first level 
child of the IWorkbenchPage, but in some cases this is not the case. (Note 
that GotoLineAction works in the PDE editor, but this is not a good example, 
since it doesn't use a MultiPageEditorPart, but rolls its own).

Unhandled exception caught in event loop.
Reason:
com/ibm/etools/ctc/flow/ui/NestedEditorSite incompatible with 
org/eclipse/ui/internal/PartSite
java.lang.ClassCastException: com/ibm/etools/ctc/flow/ui/NestedEditorSite 
incompatible with org/eclipse/ui/internal/PartSite
