This occured during the course of combat using a hunter in WoD.

1x [ADDON_ACTION_BLOCKED] AddOn 'AdiButtonAuras' tried to call the protected function 'OverrideActionBarButton3:Show()'.
!BugGrabber\BugGrabber.lua:586: in function <!BugGrabber\BugGrabber.lua:586>
[C]: in function Show' FrameXML\ActionButton.lua:301: in function <FrameXML\ActionButton.lua:275> [C]: in functionActionButton_Update'
FrameXML\ActionButton.lua:577: in function `ActionButton_OnEvent'
FrameXML\ActionButton.lua:137: in function <FrameXML\ActionButton.lua:134>

Locals:
nil

If anyone has a reliable way to reproduce it, please reopen and post it.

The only time this error occurs is when Lock and Load procs. Lock and load procs from Black Arrow.

@Cursedcruiser I got this on a monk. It very probably does not depend on the spell used.

Same here:

2x [ADDON_ACTION_BLOCKED] AddOn 'AdiButtonAuras' tried to call the protected function 'OverrideActionBarButton2:Show()'.
!BugGrabber\BugGrabber.lua:586: in function <!BugGrabber\BugGrabber.lua:586>
C: in function `Show'
FrameXML\ActionButton.lua:301: in function <FrameXML\ActionButton.lua:275>

C: in function ActionButton_Update' FrameXML\ActionButton.lua:577: in functionActionButton_OnEvent'
FrameXML\ActionButton.lua:137: in function <FrameXML\ActionButton.lua:134>

This happened to me too and I am using Dominos. However, I cannot find what causes it and reproduce it consistently.

This kind of error was happening with Inline Auras too so I have made all I could to avoid tainting the button:

• AdiButtonAuras is not calling the :Show() method of any action button.
• AdiButtonAuras creates and works with a separate frame without ever writing in the original action button.

Moreover, AdiButtonAuras does not even touch the OverrideActionBar buttons.

It looks more like something has tainted the Override bar? Which action bar mods are you using?

The only time I've seen this in the past is when using Dominos AND you've opened Dominos config during the session.

Using Bartender v4.6.5 and the button facade that's included called Zoom.
