So since i started using this addon im having some minor problems. It started on some specific bosses like Assault of the Zaqali or Zskarn or last boss in Neltarus. When ever i picked up an item from the ground (rock-trap-treasure) and as soon as i got extra action bar to use i would get an lua error and my cast bar would be gone. I tried using weak aura for cast bar and im having same problem. Now problem is here when ever i switch talents and i enter the combat (it happens like 50% of the time ). No idea how to check if addons are having some kind of conflict cos i know few people who use the same addon but they have no problems.
I have taint log if that helps in any way

seems there's something weird about your setup, since PlayerCastingBarFrame should have nothing to do with the ExtraActionButtonFrame

can you get an extra action button out of combat somewhere, and run a few chat commands, and see what the output is?

/dump ExtraActionButton1:GetParent():GetName()
/dump ExtraActionBarFrame:GetParent():GetName()
/dump ExtraActionBarFrame:GetParent():GetParent():GetName()
/dump PlayerCastingBarFrame:IsProtected()
/run local f;function f(a,b)return a:GetParent()==UIParent and b or f(a:GetParent(),b+1)end print(f(ExtraActionButton1,0),f(PlayerCastingBarFrame,0))

there's a big chance that I won't be able to help resolve the issue though, since it seems to be quite rare

Hey. Thanks for quick response. I started getting same lua error more often now. I started loosing castbar when i enter combat. It doesn't happen only on those 3 fights anymore. Just entering any combat can trigger the problem and my cast bar is gone. But i noticed something. It has much higher chance to happen when i switch my talents. So im not even sure if it has to do anything with extra action button anymore.

I did what you asked but not sure how to check what happens when i enter those chat commands. So ill just link my chat.

Dump: value=ExtraActionButton1:GetParent():GetName() [1]="ExtraActionBarFrame

Dump: value=ExtraActionBarFrame:GetParent():GetName() [1]="ExtraAbilityContainer

Dump: value=ExtraActionBarFrame:GetParent():GetParent():GetName() [1]="UIParent"

Dump: value=PlayerCastingBarFrame:IsProtected()
[1]=true,
[2]=false

And the last one is 2 0

thanks for the info, I was indeed looking just for the chat output 🙂

can you try a few more things for me
/dump PlayerCastingBarFrame:IsProtected()
right after logging in, before touching the talent tree or anything like that. With, and without TTT enabled

if it shows [1]=false, [2]=false, then try again after changing around your talents

if it shows [1]=true with TTT disabled, then try disable all addons
if it turns into [1]=false, then enable addons again, until you find the one that turns it from false, to true

basically, if you get [1]=true, it means that for some reason, a protected frame or button got attached to your cast bar (which should never happen); and somewhere down the road, TTT spreads taint into the cast bar's show/hide function
normally this is fine, as the frame should not be protected (which you can tell, by it posting [1]=false in chat)

our goal here, is to find out what addon or setting is turning it to [1]=true 🙂

if it shows [1]=true, even with all addons disabled, there's a few more debugging things that could help:
/dump PlayerCastingBarFrame:GetNumChildren()
if it's more than 1, then type /tinspect {PlayerCastingBarFrame:GetChildren()} and make a screenshot of the resulting popup
it should look something like this

So i tried with and without TTT and i would get 1 false and 2 false.
After changing talents its still false
With all addons disabled its still false

/dump PlayerCastingBarFrame:GetNumChildren() is showing as 1

So i have no idea what is happening and i don't want to waste more of your time. Im sure you are busy and i want to thank you for at least trying to help me.
