Got this from a user. My mentioned function (GetRecruitWhoList()) calls simply some who functions and prepares a table with index/displaystring

    -- get data
    numWhos, totalCount = GetNumWhoResults()
    for i = 1, totalCount
    do
        zoneOK, classOK, levelOK, noGuildOK, includeContacted, includeRefused = true, true, true, true, true, true
        
        charname, guildname, level, race, class, zone, classFileName = GetWhoInfo(i)
...

if no who list available it calls a sort on guild criteria
        SortWho("Guild")

That's all - doesn't seem a problem of my addon, more a problem of hooks into the who process or some results WIM expects.

I'm not using LibWho

What steps will reproduce the problem?
1.
2. install WIM and install guildadmin
3. click on recruiting menu

What is the expected output? What do you see instead?
lib error

What version of the product are you using?
0.0.0.4beta

Do you have an error log of what happened?
