[Bf-extensions-cvs] SVN commit: /data/svn/bf-extensions [4341] contrib/py/scripts/addons/ object_booleans.py: --- Boolean Operators v0.4 ---

[Peter D. Cassetta]

Hi Jonathan,

Just wanted to say that due to not-too-recent API changes, context is 
restricted for add-ons during activation.
So on activation your add-on will not actually be enabled, and will 
instead print the following error:

Traceback (most recent call last):
   File "/usr/lib/blender/2.66/scripts/modules/addon_utils.py", line 269, in enable
     mod = __import__(module_name)
   File "/usr/lib/blender/2.66/scripts/addons_contrib/object_booleans.py", line 15, in <module>
     scene = bpy.context.scene
AttributeError: '_RestrictContext' object has no attribute 'scene'


This line in your add-on is what causes the error:

scene = bpy.context.scene

The error occurs because scene is not a part of this restricted context.
Note that you can access bpy.context as normally inside functions and 
such, just not during activation.

Anyway, sorry if this error's been reported already, but maybe this will 
help you get an idea of what's going wrong, and how to fix it.
If you need help, I'd recommend asking on #blendercoders or e-mailing 
the bf-python at blender.org mailing list.
