Setting the action attribute for nested:form

[Vinuta Nagaraddi]

Hello,
 
I am trying to set the action attribute for the nested:form tag
dynamically.  I want to achieve this by using a property called 'url'
from the form (or maybe someone can suggest a better way).  I was
unsuccessful using the nested:write tag. Any help would be appreciated.
 
Thanks,
Vinuta
