Anyone still following this, here's what's going on: node paste does in
fact trigger the onCreate. What *doesn't* work is specifically setting a
node's input in an onCreate function when pasting.That was throwing me off.
For example, if I have a node in the DAG called 'foo' and this in my
menu.py...
###
def testSetInputOnCreate():
print 'Running test set input on create function'
n = nuke.toNode('foo')
if n:
nuke.thisNode().setInput(0, n)
nuke.addOnCreate(testSetInputOnCreate, nodeClass='Dot')
###
Create a Dot node (i.e. through the toolbar) and its input will set
correctly to 'foo'. But, if you copy and paste that same Dot node, its
input won't set. This seems like a bug. Then I tried running the function
in a thread timed with a .25 second delay. That does work.
So, for now, my problem is solved (somewhat inelegantly). Sending in a bug
report...
Cheers
