FOP 2.20.
If I clear a label in the FreePBX Module it appears to get saved properly but the input box gets re-populated and so the next time I make a change the label gets re-added.
I tested a user and a trunk and the behavior is the same in each case.
You are right... I am not sure to call this a bug or a feature. I will see what can I do as I think that mantaining the empty label is what must happen, but I also need new buttons added if there are any. I will experiment a little bit , and let you know if there are updates to the module in the near future.
Following up on this:
Empty labels are replaced with the FreePBX label when you load the buttons page. That is done on purpose. But as removing the label is also a way to prevent a button from showing in the panel without setting up groups, then I might revise this option. What do you think? Blank labels must be preserved ?
Perhaps an active/inactive flag instead?
