mayaUsd.ufe.getAllStages cannot see stage after mayaUsdProxyShape was renamed (on the first execution)

[p0las]

Describe the bug
when mayaUsdProxyShape is renamed then mayaUsd.ufe.getAllStages is not returning the stage from it in on the first run. It has to be executed twice to work.

Steps to reproduce
Steps to reproduce the behavior:

from maya import cmds
import mayaUsd

n = cmds.createNode('mayaUsdProxyShape')
cmds.connectAttr('time1.outTime', n + '.time')

maya_stage = cmds.listRelatives(n, pa=True, parent=True, ni=True)

stages_before = mayaUsd.ufe.getAllStages()

renamed_stage = cmds.rename(maya_stage, 'fooBar')

# mayaUsd.ufe.getAllStages() #without this line the assertion is going to fail

assert mayaUsd.ufe.getAllStages() == stages_before

Expected behavior
mayaUsdProxyShape should return the same stages everytime

Specs (if applicable):

• Windows 10
• Maya 2024
• maya USD plugin 0.28.0

Hello @p0las, I gave this a try on my end in Maya 2024.2 using 0.28.0 and I was not able to reproduce the error you are seeing. When I run your code the Assertion doesn't fail, it always passes regardless of whether I have line 13 commented out or not. The output of my get all stages is always the same:

print(stages_before)
[Usd.Stage.Open(rootLayer=Sdf.Find('anon:00000267FF108010:anonymousLayer1'), sessionLayer=Sdf.Find('anon:00000267FF10A530:anonymousLayer1-session.usda'))]
print(mayaUsd.ufe.getAllStages())
[Usd.Stage.Open(rootLayer=Sdf.Find('anon:00000267FF108010:anonymousLayer1'), sessionLayer=Sdf.Find('anon:00000267FF10A530:anonymousLayer1-session.usda'))]

I am curious if you print on your end how does your .getAllStages() look before and after?

you are right. I executed it on another machine running the same versions and it works fine. I have two machines that are meant to run the same pipeline yet the results are different. I will investigate this further. Thank you for taking the time to test it.
