After your next 'svn update' you need to get the latest chandlerdb version
by running in 'chandler':
make chandlerdb - OR -
make
This update makes it possible to defer commit() calls until a block of code
has completed. For example, in CollectionCanvas.py, I'm using this to defer
the commit() call made by CreateEmptyEvent() until the entire double click
processing completed:
elif self.blockItem.CanAdd():
with self.blockItem.itsView.commitDeferred():
self.OnCreateItem(unscrolledPosition)
This block of code, part of CollectionCanvas._handleDoubleClick() means to
defer all commit() calls that happen inside it until it completes. Then, if
any commit() calls happened, the last one is applied.
