When you open a file outside of the workspace (like File > Open...), 
Eclipse will use a FileStoreEditorInput (as you discovered). As far as I 
know, there is no way of knowing that MyEditorInput is supposed to match 
with MyEditor so I'm not even sure how your code originally worked in 
3.2. What are you adding to MyEditorInput that can't be satisfied by the 
framework's original IEditorInput implementations?
