Hi guys,
I've been struggling with a problem, namely ConflictErrors.
At times, a long-running process may add 100, 1000, 1
objects to a single folder. Under this process, several
ConflictErrors may be raised, but they are captured, and
the transaction committed again. Problem solved.

This would happen if, for example, you define an __init__ method in your
class, but you don't use something like:
from Globals import default__class_init__
default__class_init__(yourClass)

Does it depend on whether the product is a ZClass

Where's the documentation that I can read to get a
clue?
thanks!

If you mean to refresh the Python Scripts product, I don't know of a
reason why that wouldn't work. I just tried it and it seems to be fine.

Hi,
I've got an object which implements __setitem__ in such a way that it's
perfectly safe for use in Python Scripts. Sadly, it seems that Evan's Byte Code
hacks won't let me do this :-(
Whenever I try to do something like: myobject['fish']=1, I get a traceback like
the following:
Traceback
If I try and do:
if type(x) == type(0):
...I get a NameError on type :-(
What is so bad about type that I can't use it safely in PythonScripts?!?
frustratedly,

Hi!
So as the item is an instance of my ZClass containing also an company_name
attribute
it will always return the item and because of that the Rack thinks it's
already there.
So why is this happening? What do I need to change?

When applied to an Extension Class, it gives you access to the actual class,
rather than a nice inert type.
