[Pythoncard-devel] Error handling - what's the right thing to do.

[Alex T. <al...@tw...>]

Apologies if this is a dumb question, but I'm not sure how best to 
handle this error condition.

I discovered that if you start a Pythoncard script when the main 
script's resource file is missing, you get an error condition; the code 
in model.py/internationalResourceName() assumes that there will be at 
least one matching resource file.When there isn't, it tried to use an 
un-initialized variable .... clearly not the right thing to do.

It's easy enough to detect the situation - but what should we then do ?

See below for the diff of my current version showing the problem .....
