    partial refresh for portlets (server-side implications)

      Hi,

      I have been reading about the Partial Refresh support in the JBoss forum. I had a very nasty problem with the WebSphere Portal in that whatever kind of AJAX you use with JSF components, all other portlets on the page are re-rendered again. It looks like for that Portal, the only way to have "real" ajax , and avoid the server-side overhead, is to point the XMLHttpRequests to an external servlet that will serve them. But IMO that's really a hack and not a clean solution at all, because it breaks the whole idea of a "Portal".

      I have seen that JBoss has the feature "partial refresh". Here is my question:

      If i have my own JSF AJAX framework (with custom render-response phase listener for instance) , and I do a XMLHttpRequest to the portal, will it automatically render() all of the other portlets on the page ? If yes, is there any configuration parameter that I can use to avoid that and to render only the portlet that caused the Action Request ? Will the "partial refresh" property work fine , even though I am not using the ajax4jsf portal support?

      Thanks very much for your feedback.

      Regards,
      Angel

          Partial refresh does not use ajax4jsf.
          Actually it's purpose is to have a refresh of a unique window at a time, that portlet does not have to use any AJAX technology.

            Thomas, are you saying that I can benefit from partial refresh using only JSR 168 and JBOSS 2.6.5SP1? For example, if I have a JSP that has a form with a button, and I'd like that button to cause only that portlet to refresh, this can be accomplished?

            To clarify, currently my JSP has code similar to this:

            <form action="<%=renderResp.createActionURL().toString()%>" method="POST">
 <select>
 <option value="volvo">Volvo</option>
 <option value="saab">Saab</option>
 <option value="mercedes">Mercedes</option>
 <option value="audi">Audi</option>
 </select>
 <input TYPE="SUBMIT">
</form>


            And hitting the SUBMIT button always causes a full portal refresh. How can I fix it so that it only causes a portlet refresh?

            I have been searching for the answer to this for several days, with no luck, in both the JBOSS documentation and elsewhere. I am a web noob though, so maybe it's just something simple. I would be happy to pay for a quick solution, if any exists, I've wasted so much time already.

                For anyone who tracks this the other post is:
                http://www.jboss.org/index.html?module=bb&op=viewtopic&t=124550

                I didn't find it helpful though, I've read that documentation over and over. I will look through the samples. That failing, I will look into the paid services, I wish it was as simple as "I can do that for $75 USD, send to paypal account X" or something.
