Is it possible to have form elements in a dijit.Dialog that get POST'd when the form is submitted? For example in the following code (adapted from the dijit.Dialog example in the docs):

Dialog demo
    
        @import "http://o.aolcdn.com/dojo/1.0/dijit/themes/tundra/tundra.css";
        @import "http://o.aolcdn.com/dojo/1.0/dojo/resources/dojo.css"
    
    
    
       dojo.require("dojo.parser");
       dojo.require("dijit.form.Button");
       dojo.require("dijit.Dialog");
       dojo.require("dijit.form.TextBox");

       function checkPw(dialogFields) {
          alert(dialogFields.confirmpw); 
       }

                        OK
        
    

This works as expected (displaying whatever you put in the textbox in an alert). However, if I remove the 'dojoType="dijit.form.TextBox' from the then the value isn't passed on.

I'm particularly interested in this as I'd like to have a file upload element in a form in a Dialog and there doesn't appear to be a dijit.form.input type I can use. I see dojox.widget.FileInput but it's not clear that's going to work reliably (being in dojox and all). I'd be happier if I could just get a standard to work.
