Hi Nukers,

There's a quite simple behavior that seems a bit weird (at least for me), 
surely a bug (is it known ?)
A Cascading_Pulldown_Choice knob doesn't keep its display after a recreation 
(copy/paste or comp reload)

To illustrate, just copy/paste/execute the following snippet

/code/
noop = nuke.createNode("NoOp")
preset_list = ["item1/sub1", "item1/sub2", "item2/sub1", "item2/sub2"]
pulldown = nuke.CascadingEnumeration_Knob("preset", "Preset", preset_list)
noop.addKnob(pulldown)
/code/

Copy/paste the resulting node and examine the new pulldown, it doesn't keep its 
cascading structure.
It's now just a simple Pulldown_Choice without cascading capabilities.

Any known workaround ?
Cheers,
philhub
