All classes are fields in lz? Why's that?
That seems kinda odd.

I have some window management code that iterates through an array
of different windows & switches on the exact window type.
It used to work with code like this -
var w=getNextWindow();
// classname can be composewindow, mailwindow,
contactswindow
if(w.classname == "composewindow")
{ return w;
}
This stopped working because w.classname is now Object.
w.constructor.classname is, however, 'composewindow'
What's the right way to do this? Should obj.classname be the
same as obj.constructor.classname?
I want to make sure this works when & if OpenLaszlo is updated.
I think what you really want to do is say:
if (w instanceof lz.composewindow) {
The fact that there is a classname property on instances is an
accident of Javascript inheritance.
