Re: [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

Hi Don,

I'm converting the data classes to use mixin and ran into a problem 
when the constructor takes multiple arguments.


Here's a test case:


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

mixin Mixin {
   var _mixin = null;
}

class Testing extends Base with Mixin {

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

}

This produces the following error:

      [java] ERRORS:
      [java] Compiler error: at [(unknown): 6]: Error: Incorrect
number of arguments.  Expected no more than 0.
      [java]
      [java] super(arg1, arg2, arg3, arg4)
      [java]                          ^


Thanks!
