This issue appeared after the 8.1 update and/or the latest WA update.

I'm having a set of icons which are displaying either custom text such as

function()
local boolResult = "no data";

local nbCharges,bsMaxCharges,bsStartTime,bsDuration = GetSpellCharges("Barbed Shot");

return nbCharges;

end

or simply display stacks %s

but now, after each reload or reconnection, the text value will not be shown until i edit the wa, uncheck the "text" checkbox and then re-check it.

Not sure it's related but this is a WA exception i m getting on login

Message: Interface\AddOns\WeakAuras\Locales\ruRU.lua:616: unfinished long string near ''

Stack: Interface\AddOns\WeakAuras\Locales\ruRU.lua:616: unfinished long string near ''

That's unrelated and already fixed.

Also if i edit the custom function and save it, the text show up again (until next reload)

That should be fixed in 2.10.8

I can confirm this issue is happening with my WA that shows quest counts as well.

function()
    local _,num = GetNumQuestLogEntries()
    return num
end

I have to go into the WA and edit it and then all WA text shows up.

it seems to be related to #1017
