We didn’t really consider that case.


I wonder if you could send a veto with a message to the screen, but keep track that you just vetoed it (in an expirable in memory cache with a MultiKey with the userid, groupname, value, etc), and if you get that same request again in a certain period of time, then you know the user had been warned and not veto it…


If you just want the hook to throw a message on the screen and let it complete the first time, I think you would have to edit the UI code for that…

I previously used a group hook to block the group creation by throwing a HookVeto. Right now I’m wondering if it’s possible to send a warning to the user using the Hook but still have the process complete.


My use case would be :

Using a AttributeAssignValueHooks, prevent invalid values (<= 0) and show a warning if the user uses a low value (0 < val < 5) that could possibly have bad consequences, but still let the value be set since it might be the right value for them.
