Hi there,
I just started porting an app to beta 2 from 1.1 and I am having some
problems with javascript on the page. It is a simple login page where a
java script function posts the form when a button is pressed. But I get
the following error when i double click on the "Done" icon at the
bottom of the page:
'document.formLogin' is null or not an object
code: 0
The same page works fine on 1.1. I am running ASP.NET beta 2 on a virtual machine with an XP image on it
Here are the markup and code behind files:
