I tried to check it out, but I can't deal with that error. It's
Interface\AddOns\GridStatusRaidDebuff\Core.lua:250: attempt to call method 'IsEventRegistered' (a nil value)
The corresponding line is
if self:IsEventRegistered("COMBAT_LOG_EVENT_UNFILTERED") then
Can someone with knowledge give a hint what's going on here? IsEventRegistered is a method of any frame afaik, and there are hundreds of calls to self before that, so I don't see why that shouldn't work here.
Thanks for any pointers, I'd really like to get that going again.
Specifically, to resolve the error you posted, you need to simply remove the check to see if an event is registered. AceEvent-2.0 provided the IsEventRegistered method, and threw errors if you tried to register an event that was already registered, or unregister an event that wasn't registered. AceEvent-3.0 doesn't provide any such method; neither it nor the default UI throw errors if you register an already-registered event or unregister a non-registered event. If the plugin is using that check to determine something other than simply "is this event already registered" you'll need to find an alternate method of doing so. If you're confused, post the section of code surrounding the check.
I'd like to have permission to upload that with my whole UI as a pack on wowinterface and curse, if possible including future versions to keep the pack up to date. Afaik, the original authors are not active anymore, so what can I do here? Can this project be reassigned or something?
The license is listed as "All Rights Reserved" so it can't be reassigned. I sent a forum PM to Azethoth a week ago asking him to review it, bump the toc, and tag it for release. It looks like he hasn't logged in since. If I don't hear back soon, I'll bump the toc and petition an admin to tag it.
