(Using dojo 1.1.1)
Can anyone spot why the parent class's constructor is not called when constructing a new instance of my class?

It also creates the mySelect widget but fails to assign it to input#myNode.

A newbie question on inheritance.

I wish to define several FilteringSelect objects. Those various objects differ only in their store and their prompt message. In order not to repeat myself, I am therefore tempted to declare a new class: MyFilteringSelect, which would predefine all the other parameters. Something like this:

this.autoComplete = false;
this.hasDownArrow = false;
this.labelAttr = "name";
this.queryExpr = "${0}*";
this.searchDelay = 0;
}
