[Laszlo-dev] Mixin problem

[Philip Romanik]

Hi Don,

I confirmed that your solution works. If I define a constructor in 
the mixin everything is fine:


class Base {
   function Base ( arg1:* = null, arg2:* = null, arg3:* = null, 
arg4:*  = null){
   }
}

mixin Mixin {
   function Mixin ( arg1:* = null, arg2:* = null, arg3:* = null, 
arg4:*  = null)
   {
     super(arg1, arg2, arg3, arg4);
   }
   var _mixin = null;
}

class Testing extends Base with Mixin {

   function Testing ( arg1:* = null, arg2:* = null, arg3:* = null, 
arg4:*  = null) {
     super(arg1,arg2,arg3,arg4);
   }

}


Thanks!

Phil
