[Trigger] Add trained hero to unit group don't work

[Sxar]

I have been working on this code all the night. I already tryed to solve the inssue by myself before post here. The problem is that the code don't add the unit to unit group. I don't know why.

function Trig_BladeMasterSet_Conditions takes nothing returns boolean
    if ( not ( IsUnitType(GetTrainedUnit(), UNIT_TYPE_HERO) == true ) ) then
        return false
    endif
    return true
endfunction

function Trig_BladeMasterSet_Func007C takes nothing returns boolean
    if ( not ( 'Obla' == GetUnitTypeId(GetTrainedUnit()) ) ) then
        return false
    endif
    return true
endfunction

function Trig_BladeMasterSet_Actions takes nothing returns nothing
    set udg_DemonNumber = 1
    call GroupAddUnitSimple( GetTrainedUnit(), udg_BlademasterDeathlist[2] )
    call GroupAddUnitSimple( GetTrainedUnit(), udg_BlademasterDeathlist[1] )
    call GroupAddUnitSimple( GetTrainedUnit(), udg_BlademasterDeathlist[3] )
    call GroupAddUnitSimple( GetTrainedUnit(), udg_BlademasterDeathlist[4] )
    if ( Trig_BladeMasterSet_Func007C() ) then
        set udg_BlademasterCounter = ( udg_BlademasterCounter + 1 )
        set udg_Blademaster[udg_BlademasterCounter] = GetTrainedUnit()
        set udg_BlademasterOwner[udg_BlademasterCounter] = GetOwningPlayer(GetTrainedUnit())
    else
    endif
endfunction

//===========================================================================
function InitTrig_BladeMasterSet takes nothing returns nothing
    set gg_trg_BladeMasterSet = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_BladeMasterSet, EVENT_PLAYER_UNIT_TRAIN_FINISH )
    call TriggerAddCondition( gg_trg_BladeMasterSet, Condition( function Trig_BladeMasterSet_Conditions ) )
    call TriggerAddAction( gg_trg_BladeMasterSet, function Trig_BladeMasterSet_Actions )
endfunction

As you can see there are four unit groups (bleadmasterdeathlist) that must add the created hero but I don't know why it don't work. orz

 

[Sxar]

I know the conditions are fullfilled because "demonnumber" variable is a flag that I'm using for debug, however the unitgroup function is not working orz

You can Use JASS tags instead of CODE.
Ensure the groups exist, check this: [Solved] - units wont attack-move location

 

[Dr Super Good]

Unit groups are complex objects while the group variables are references to a unit group object. One has to make sure that a group variable or array references an existing unit group object for one to be able to add, remove or iterate units with it.
