Refreshing a portlet

How do I refresh the portlets?

Lets say I have a page in which there are 4 portlets. After submitting a form in the active portlet I should be able to refresh other three portlets. Is there any api or tags to do this?

I would appreciate if anyone can respond to this question.

Thanks

Re: Refreshing a portlet

What do you mean with "refresh"?

I had a problem a time ago, when I submit a form or navigate through the active portlet I missed all the servlet request parameters and all the parameters from other portlets and this portlets stopped working well.

Perhaps these issues are related.

When I submit the form whether the other portlets will get fresh hit or just a cached version.

The other portlets are in render request and the portlet you submit is in action request. The behaviour is diferent in each case.
