Comment 1 Nam Nguyen 2006-07-12 21:12:15 UTC 
I am not sure I understand step 4 'Go To -> Schema'.  Does it means switch to
Schema view ?
Comment 2 Nam Nguyen 2006-07-12 22:26:28 UTC 
Just from the top of the stack I guess that axim does not check for null on
returned of factory create call in populateChildren implementation?  Cc'ing Sam
for comment.
