I put the validation check in the following code and it seems to no longer allow the keylistener i added for the dialog to work. any ideas?

form validation code: if (!loginForm.isValid())

key listener code: loginDlg.addKeyListener(13, Login.Control, loginDlg);



<link rel="stylesheet" type="text/css" href="resources/css/ext-all.css" />

emailField.focus(); // set focus on form field once the dialog has been rendered
},

Control:function() {
///////////// here's the validation check

I'm not sure and I haven't tested it but it looks to me that Login.Control will never be called if the input is not valid.

Do you know where my call to the "alert box popup for the invalid input" should go if invalid input doesn't call the Control function?

I'm confused because if you click the Login button the popup shows up but if you just hit enter it doesn't. So invalid input doesn't seem to be preventing the form from being submitted since you can still click the button. Why does the keylistener not work when the input is invalid?
