I am trying to query for the default expression used in the imagePlane with
the following code:
# Part01
img = cmds.imagePlane()
frame_ext_attr = "{0}.useFrameExtension".format(img[0])
cmds.setAttr(frame_ext_attr, True)
# Part02
print '>>> ', cmds.listConnections("{0}.frameExtension".format(img[0]))
If I am running the above code block as a whole, the return result in
`Part02` is `None`.
However, if I run them in 2 parts, `Part02` will then be returning me
`['expression1']` as the result.
Why are there 2 different results?
I have tried using some mel-based commands such as `refreshAE` or `updateAE
<node path>`, in hope that the (whole) code block will be able to capture
the expression in the first run, but it is not.
Any ideas?
