I'm continually getting that error. If i try to click on the minimapbutton..it'll expand with all my other minimpabuttons but it won't close up. Some of my minimap buttons that used to be anchored to MBB..are now separated and back onto my minimap area.
As a temporary workaround, around line 418, change the code to read:
buttonframe.Hide = function(...)
local innerframe = select(1, ...);
if (innerframe:GetName() ~= "LibRockConfig-1.0_MinimapButton") then
MBB_Debug("Hiding innerframe: " .. innerframe:GetName());
--if( innerframe.hasParentFrame ) then
local parent = innerframe:GetParent();
innerframe.isvisible = false;
if( not MBB_IsInArray(MBB_Exclude, innerframe:GetName()) ) then
Warning: This is NOT the "proper" solution. Hope the MBB author is watching and can come up with a better fix. Or maybe the LibRockConfig author knows how to change his addon so MBB doesn't have this problem.
