That's a very strange error indeed... I have a feeling the traceback might
be misleading, and that something lower in Nuke is actually throwing an
exception, which is being propagated improperly. The fact that this involves
a new knob type seems suspicious as well.
I would definitely send that to support.

Subject: [Nuke-python] Setting Text2 font knob on callback
Hi,
I am having trouble setting Text2's font knob from callback,
and it gives out following error:
Traceback (most recent call last):
File "C:/Program Files/Nuke8.0v3/plugins\nuke\callbacks.py", line 127, in
knobChanged
_doCallbacks(knobChangeds)
File "C:/Program Files/Nuke8.0v3/plugins\nuke\callbacks.py", line 44, in
_doCallbacks
for f in list:
TypeError: an integer is required
Following is a code that reproduce the error:
n = nuke.createNode("Text2")
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("Utopia", "Regular")
else:
node["font"].setValue("Courier", "Regular")
nuke.addKnobChanged(knob_callback, nodeClass=n.Class())
n["test"].setValue(2)
Does anyone know why python is raising TypeError?
I've never seen a error like this in a for statement.
Thanks,
Taku
