Hi,
I have two editors A and B. From A I try to open a B editor with
getSite().getPage().openEditor(BInput, BEditor.ID);
this runs into BInput.equals(Object obj) to check if there is already a BEditor open for this input.
But, strangely obj is an AInput instead of a BInput, so my compare code runs into a ClassCastException.
Has anybody an idea what went wrong?
Thanks,
Juergen
