Does not show the progress bar... V12

[skukered]

I am testing in the v12...
Why does the progress bar not load when I run the method?

But if I run it, I restart the odoo service, without updating the page I run the method again, yes, it shows it

It may not work for the first time, because the grey waiting-screen is activated (created if not existing yet) only after a couple of seconds of waiting and it may miss the first progress notification. Typically, the second progress notification shall make the progress bar visible. The progress notifications are sent every 5 sec., so the longest time the user waits before any progress is visible shall be no longer than 10 seconds, provided the iteration in progress is ongoing and each step takes less than 5 sec.

It may work for the second time, because the grey waiting-screen is already created (just invisible), so it does not miss the first notification.

However, in order to be sure, you would have to analyse the sequence of execution in browser debugger.
