            handler: function() {
                var firstName = Ext.fly(firstName).getValue();
                //var tmpParams = this.User.form.getValues();
                alert(firstName);
            }
        },
        {
            text: 'cancel'
        }]
    });

Where did you read about Ext.fly?

[steffenk]

what do you see?
var firstName = Ext.fly(firstName).getValue();

HI,
I've gone through the Ext doc at this location http://www.extjs.com/deploy/dev/docs/ I tried Ext.fly and Ext.get,I'm getting null.

[steffenk]

again, you obvious don't read exact.

var firstName = Ext.fly(firstName).getValue();
with var firstName you declare a var which is NULL
Ext.fly(firstName).getValue(); you try to get a field with name of the declared var.

firstName != FirstName

Also, you are using documentation for the wrong version!

http://extjs.com/deploy/ext-3.0-rc3/docs/

Now, are those methods what you need?
