Need some help with secure frames and target unit

[Duugu]

Hi all.

If I create a a button that inherits SecureUnitButtonTemplate and do the following:

buttonobjekt:SetAttribute("type1", "spell");
buttonobjekt:SetAttribute("unit1", "raid2");
buttonobjekt:SetAttribute("spell1", "a spell");

shouldn't this create a button where "a spell" for target "raid2" is casted on left mouse button??!??

My problem is ... doesn't matter what I use for buttonobjekt:SetAttribute("unit1", "a unit"); ... the spell is casted on myself.

I'm confused. Could someone please help me out of that?
