I am writing a page that asks a user to select an option, if the option is not available I would like to display a modal window allow the user to input some data and click a button.  The button would then update the database with the option and I would need to return to the orignal page and redisplay the data with the new option selected.  My problem is that I am not very good at java and would like to do the update in the code behind.  Is that possible in a a web dialog box?  If not what are my options?  Pass the data back to the original page and update it from there?
