[Pythonmac-SIG] Found my OSA problem !

[Alexandre Parenteau]

Jack,

I've been telling you over and over I had some AppleScript problems, events
not returning. For example I use Make_Project of CodeWarrior.
Metrowerks_Shell_Suite.py, and it never returned an error when the project
was failing.

The solution came for me around the aetools.unpackevent:

    try:
        dirobj = ae.AEGetParamDesc('----', '****')
    except AE.Error:
        pass
    else:
        parameters['----'] = unpack(dirobj, formodulename)
        del dirobj

If I understand correctly, it is expected there is an event of type '----'
to return an error. Well, maybe it used to, but not anymore for me on
Jaguar. Instead, I get directly the 'errn' event coming back. So I changed
the code this way :

   try:
        dirobj = ae.AEGetParamDesc('----', '****')
    except AE.Error:
        try:
            keyword, dirobj = ae.AEGetNthDesc(1, '****')
        except AE.Error:
            pass
        else:
            parameters[keyword] = unpack(dirobj, formodulename)
    else:
        parameters['----'] = unpack(dirobj, formodulename)
        del dirobj

Note I don't like this code, may be I should use AECountItems.

Anyway, that was the source of my problem. How come you don't experience
that ??? I don't understand ! Why the returned event suddenly changed from
'----' (and then 'errn' inside the AEList) to directly 'errn' ?

Anyway, if it could make it for 2.2.2, I want to emphasize that without
this, I don't have CodeWarrior.CodeWarrior functional (tested on CW 7.1,
7.2, 8.0, 8.1, 8.2, Py2.2.1, Py2.3a0, re-generating CodeWarrior.CodeWarrior
or not). 

Alex.
