[FEATURE] ILIASObject: remove ilProgressBar usage

[thibsy]

Hi @kergomard,

I have replaced the legacy ilProgressBar usage as fast and good as I could. I am not quite sure, if this code is actually reachable, because when copying multiple (nested) objects, the page simply loads without ever showing the ilObjectCopyProgressTableGUI table. Maybe you can try this out yourself?

Also note, I have replaced the legacy usage as is. I believe we should not render multiple progress bars on this page in the future, but instead use one progress bar to cover the progress of all objects being copied. I also needed to provide the _max_steps as an URL parameter, because there is (currently) no way to ping-pong the max-value of the progress bar.

Further note, this PR contains an additional commit which needs to be merged first. see #8268

Kind regards,
@thibsy

Hi @thibsy

Thank you very much for the PR!

I finally got around to looking into this. I started by having a look at the functionality and sadly, this is not working as expected yet, so I would kindly ask you to have another look at it.

To be able to test it.

• You need a category (or a course) with multiple objects in it.
• You need to fix the soap-endpoint here (for me it was enough to just remove '/public' from the endpoint, ...but there might be more issues than that.

What isn't working (as far as I can see):

• The progress bar is never updated, but disappears right away.
• There should be a redirect once the copying has finished. We either never get there or it is not working.

I only read cursorily through the code and thus right now only have two minor, purely formal change requests:

• Could you please use the standard comparison order here. From where I stand code becomes harder to read this way around.
• Please move the usages of namespaces here with aliases (DataFactory, UIRenderer, UIFactory).

Thanks again and best,
@kergomard
