Hi,
the problem is that in your example the scope from your listener
function is wrong, when the function is called. The 'this' doesn't point
to the LoginWindow to set the right scope use that instead:
this.__widgets["okbutton"].addListener( "click", function(e)
{
alert(this.__widgets["namefield"].getValue());
}, this); //<-- set the right scope for the 'this'
Cheers,
Chris
