Hi all,

I have an exception, when i try to use MultiEditorInput,as follow
MultiEditorInput mei= new MultiEditorInput(editor.ID, editorInput);
configurer.getWindow().getActivePage().openEditor(mei, MyEditor.ID);
It was working fine with my RCP application, but when i convert my plugin
to RAP plugin i got this exception .
However, when i open the editor directly using Editor ID and the
editorinput, it works fine ;like this :
configurer.getWindow().getActivePage().openEditor(MyEditorIn put,
MyEditor.ID);

This is the exception i got:

Hi,

looking at the stacktrace I wonder how IncidentEditor#setInput() is able to
produce a ClassCastException. I assume that #setInput() is the inherited or
overridden method defined in EditorPart. The original method does nothing
but assigning a field with the given parameter. Not much room for a CCE.
Does your editor implementation override #setInput() and if so how does it
look like?

As you've said that there's a RCP version of the editor, do you develop and
test the RAP app against a different target than the RCP app? I ask, because
I want to exclude that a mixed up RCP/RAP runtime causes that CCE.

Ciao
Frank
