I believe that the keybinding for class/group sorting should be one of the bugs fixed in the next release of CT_Raidassist (I haven't heard a time frame yet).
If you don't mind editing the lua file yourself, you can fix it by editing the CT_RaidAssist.lua file (around line 4149). There you will find a CT_RA_ToggleGroupSort() function which should be replaced with an updated version. Keep in mind that due to Blizzard restrictions, it is not possible to toggle between class and group sorting during combat.
In version 1.621 of CT_RaidAssist, the original function looks like this:
Code:
function CT_RA_ToggleGroupSort()
local tempOptions = CT_RAMenu_Options["temp"];
if ( tempOptions["SORTTYPE"] == "group" ) then
CT_RA_SetSortType("class");
else
CT_RA_SetSortType("group");
end
CT_RA_UpdateRaidGroup(3);
CT_RA_UpdateMTs(true);
CT_RA_UpdatePTs(true);
CT_RAOptions_UpdateGroups();
end
You need to replace those lines of code with these:
Code:
function CT_RA_ToggleGroupSort()
if (InCombatLockdown()) then
return;
end
local tempOptions = CT_RAMenu_Options["temp"];
if ( tempOptions["SORTTYPE"] == "group" ) then
CT_RA_SetSortType("class");
else
CT_RA_SetSortType("group");
end
CT_RA_UpdateRaidGroup(0);
CT_RA_UpdateRaidFrameOptions();
CT_RAOptions_UpdateGroups();
end
