[Laszlo-dev] Continued: swf9 and attribute constraint peculiarity

[Rami Ojares / AMG Oy]

It probably has something to do with the dependencies...
Maybe my code is incorrect when it refers to "parent.someArr.length" in 
the constraint?
Am I allowed only to refer to attribute names of laszlo nodes in 
constraints?
So that dependencies can be constructed properly.
