I'm using a custom validation method that is doing an server-side check of the data entered into a form to determine uniqueness before the form is submitted. The eager validation, while useful for client- side validation, introduces a certain amount of lag into my form which I'd like to avoid. Is there any way to turn off the eager validation after the first attempt at submission (i.e. the form only gets validated whenever the user presses the submit button)? Thanks in advance for any advice.
