Infotext bug

[wcde]

Not working with dev branch Auto1111. At webui start get this:

*** Error calling: F:\AI\stable-diffusion-webui\extensions\sd-webui-freeu\scripts\freeu.py/ui
    Traceback (most recent call last):
      File "F:\AI\stable-diffusion-webui\modules\scripts.py", line 402, in wrap_call

    AttributeError: 'NoneType' object has no attribute '_id'

After opening web-interface, Auto1111 crashes with this:

Traceback (most recent call last):
  File "F:\AI\stable-diffusion-webui\venv\lib\site-packages\gradio\routes.py", line 488, in run_predict

    raise ValueError(
ValueError: An event handler didn't receive enough output values (needed: 310, received: 2).

Without calling schedule_infotext.change() it works fine. Passed steps_component is None.

Ah I thought I could rely on component creation order when creating the ui. I'll make it so that order does not matter.

[ljleb]

Pushed a fix, let me know if the problem persists.

[wcde]

Still same error on startup. But now webui doesn't crash.

[ljleb]

I tested on the dev branch and I'm unable to reproduce. I think for some reason the components with elem_id="{tab}_steps" are not caught by the on_before_component callback. Maybe an extension messing with stuff?

[wcde]

Disabling all extensions does not help. I did some testing and it looks like some combination of webui settings is causing the error. It's hard to say what exactly, but clean config does not cause errors.

[ljleb]

Is it related to one of these options?

[wcde]

Yes, error if ui_reorder non-default.

[ljleb]

My bad, callback should be called on after component, not before. Should be fixed now.
