title: Accepting input in popup before submitting the actual form
body: <p>I am developing an application using Springs 2.0.</p>
  
  <p>I have a requirement that when user clicks on a submit button on a form, a poup should be displayed showing a "select" box for selecting a predefined reasons and a "Textarea" to accept comment. (These dropdown options are picked from context so can not use static HTML page.)</p>
  
  <p>These 2 values should also be stored in the database along with the other data fields in the parent form. </p>
  
  <p>My problem is: if I use "window.open" then the parent form data does not get carried to child window as it is not "submitted". Also can not submit the form as it will not display popup window.</p>
  
  <p>I tried searching for solution on sites, but could not find solution suitable for me.
  Any help would be really appreicated.</p>
  
  <p>Thanks.</p>
