For example, trying to setup a .yml 1-click install of a meta-package which includes repository changes while having another YaST2 process open such as Software Management, will result in an error dialog in the secondary 1-click install window "Perform Installation".

An error occurred while initializing the software repository.

Close this application before trying again.

Try again?

It gives buttons YES and NO

Clicking Yes, does apparently not try again, it brings up a new dialog about "Server & Directory" which gives an empty texbox for "Repository Name", and a populated texbox for "URL of the Repository"

It gives buttons OK and CANCEL

Clicking Cancel (not changing anything), brings up another dialog with an error message:

An error occurred while initializing the software repository.
Details:
Url scheme is a required component
Try again?

It gives buttons YES and NO

Clicking Yes, does apparently not try again (but takes a short moment), it brings up ontop a new and similar but different dialog to enter "Repository Name" and (just) "URL", without the radio buttons to edit the whole or parts of the URL and the dialog is titled "Repository URL" and not "Server & Directory". Is this intended, what's the difference? I am . All of the textboxes are empty, so it does not reference the default URL it referenced from the earlier similar dialog. 

Trying to Click OK correctly states shows a smaller dialog ontop that "URL cannot be empty" and provides an OK button.

Clicking Cancel simply closes this "Repository URL" dialog and waits in the previous dialo

Clicking No here, correctly proceeds to the next step, in this case there is another different repository URL which it also expectedly fails.

----

Perhaps it should actually try again when answering to the question in affirmative, and another button could offer to edit the URL and let it go into that loop in a different way, perhaps after failing the second or third time. And then there is the use of a different (lesser featured) dialog for subsequent fails.

On a larger note, funamentally if it does detect another YaST2 process is indeed running perhaps the error message and dialog procedure could be a bit different in such a case, so that the simplest error to fix, closing another runnign process, is mentioned first in the error message, before going into the edit URL dialogs at all. Or rather that the check for another process happens much earlier, before even starting the "Perform Installation" window and the Loading ... steps it does for a while before these dialogs come up.

However this is a minor thing as the primary error message does indeed include the relevant information about the running process and I did eventually read it in full and solved the issue, but since I'm currently totally new to OpenSUSE (and Linux distros for 24/7 usage in general) I thought to take this simple example to register and write my first (possible) bug report with, while trying to learn the proper way first without finding excuses for purely convenience fixes ofcourse.
