calling flipbook function from custom panel

hi, i create my panel , it’s very simple panel with only one button, this button suppose to do the flipbook, here’s the code :

Code:

from nukescripts.panels import PythonPanel class test(PythonPanel) : def __init__(self,title,id): PythonPanel.__init__(self,title,id) self.but=nuke.PyScript_Knob('button','button') self.addKnob(self.but) def knobChanged(self,knob): self.flip() def flip(self): nukescripts.flipbook(nukescripts.framecycler_this, nuke.selectedNode(), ("1,5", ["main"]) )

then instantiate the panel using :

Code:

m=test('testpanel','123') m.show()

select any node to render (in my example i select a Colorbar Node) ,then press the button, i got bunch of error messg, the last line said :
ValueError: ColorBars1.first_frame cannot be turned into a number

the script is working fine, as i tested on script editor without problem, the code below is working perfectly :

Code:

m.flip()

So the problem i cannot call the ‘nukescripts.flipbook()’ function by using the panel. Anyone got the solution?

thanx
