hi Fedor

from your description I'm not totally clear what role the urlController 
plays - plus its name is very suggestive of a controller as in 
model-view-controller - although it seems it is your view component.

However I think I know what the issue is - you want to seperate the 
logic for handling a form submission from the logic for a form 

 From discussions these days it appears this issue is something that 
everyone wants the next generation of struts / jsf / whatever to 
address, since struts doesn't address it directly now.

You can use another action to populate the form bean - in the forward of 
the first action, point it to the URL of a new action. You can even make 
it a redirect and the page will display with the appropriate 
human-readable URL, if that's important to you. It's known as the 
Post-Redirect-Get pattern.

Hope this addresses your question!
