I do not understand why but it looks really a problem with text selection
It's not a problem with text selection.
The problem is that profStef next changes the contents of the morph
(with setText:).
Nothing anormal here but, while doing so it kills the editor from where
the selection is evaluated.
See the portion of #evaluateSelection given below:
--------------------
evaluateSelection
...
result := [
rcvr class evaluatorClass new
evaluate: self selectionForDoitAsStream
in: ctxt
to: rcvr
notifying: self <------***** the problem is here *****
ifFail: [FakeClassPool adopt: nil. ^ #failedDoit]
logged: true.
]
...
-----------------
The receiver is passed as the requestor and it is bad because after the
selection has been evaluated,
the receiver is destroyed by the #setText: and a new editor is built.
After having evaluated the selection, the compiler sends several
messages to the requestor.
Then it crashes because the requestor is destroyed by the evaluation ... :)
So the solution is to set the editor morph as the requestor (which is
stable), not the editor.
