Ajax form submit using action URL

[Mike Skit]

Hi All,
I am trying to submit a form using xhrPost with actionUrl and expect part of the page to be updated with the reponse.
The problem is : Since the lifecycle goes thru doView, the whole page is rendered on the target div.
So what i have is a Complete view inside a already rendered view.

I dont want to use resourceurl for the above.

Basically, Is it possible to refresh a section of the already rendered porlet page with ajax call using actionURL ?

Thanks,
-Mike
