Author: Paul
Trac: http://trac.dabodev.com/changeset/6819
Changed:
U trunk/dabo/lib/eventMixin.py
Log:
I removed some code in raiseEvent in r6755 that I thought wasn't necessary,
but apparently it is. This commit reverts that change. The following commit
will update the comments in the affected area of the code.
