Hi.
I can't seem to reproduce the error on nuke 7 (I'm assuming you're using
nuke 8 since I don't seem to have a node called Text2).
Maybe the value of an enumeration knob in nuke 8 would be returned as an
int, so maybe using if key == 1 would work? That's the only type error I
could see here..
I tried your code almost similarly but changing from Text2 to Text and it
worked fine:
n = nuke.createNode("Text")
knob = nuke.Enumeration_Knob("test", "test", ["1", "2"])
n.addKnob(knob)
def knob_callback():
node = nuke.thisNode()
knob = nuke.thisKnob()
knob_name = knob.name()
if knob_name == "test":
key = knob.value()
if key == "1":
node["font"].setValue("path1")
else:
node["font"].setValue("path2")
nuke.addKnobChanged(knob_callback, nodeClass=n.Class())
n["test"].setValue(2)
