GroupEnum... not working?

[Rui]

There have been several occasions where GroupEnum functions do nothing.

For example, I was trying to do pick every unit in a radius, and then send them to another location (set by coordinates). Anyway, that matters little.
[JASS=The scripting is based around this]function ScriptExample takes nothing returns nothing
local group groupname = CreateGroup()
call GroupEnumUnitsInRange(groupname, X, Y, radius, Condition(function ThatContainsUnitTypeChecks))
call ForGroup(groupname, function actions)
call DestroyGroup(groupname)
set groupname = null
endfunction[/code]
What is wrong with this? Do the ForGroup or DestroyGroup natives work too fast for GroupEnum?

EDIT: By the way I hope I don't need to say "Don't be afraid to answer?"

It works just fine for me...

Try printing a message containing the number of units in groupname, then check if it's the same as what you're expecting?

A possible sollution might be removing the ForGroup function and making a custom loop ala

loop
    set unit = FirstOfGroup(groupname)
    exitwhen unit = null
    call GroupRemoveUnit(unit, groupname) // not sure if this is the correct name of the function
    // Do stuff with the unit
endloop

The number of units is probably 0, if the ForGroup does not work. The units just stand there as if nothing had ever happened.
