Thanks, Jesse! Not to beat a dead horse here, but for the sake of posterity:
Without stack trace enabled, Maya 2011+ won't print a custom exception
message for a derived class, but *WILL* print it if you just call the base
class. For example:
class SelectionError(Exception):
def __init__(self, value):
self.value = value
def __str__(self):
return self.value
try: raise SelectionError('You selected too many objects')
except: raise
will print
# Error: SelectionError: file <maya console> line 1: #
However, just doing this
try: raise Exception('You selected too many objects')
except: raise
will print this
# Error: Exception: file <maya console> line 1: You selected too many
objects #
