Action method call on dropdown value change

[pradeep_nayak]

Hi

I'm using richfaces 4 final version.

I need to call an action method on value change of  dropdown.

Is there any way I can achieve this ?  In the previous versions of richfaces  a4j:ajax  had the ' action'  attribute which used to call the specified action method. But in the latest version i do not see this attribute?  Is there any replacement ?

On value change I need to render a different page. As of now i'm using a value change listener and forward to another page using facesCtx api.

Thanks

Pradeep

it can be done with a4j:jsFunction :

<h:selectOneMenu id="select"

                         value="#{optionTree.value}">

            <f:selectItem itemLabel="1" itemValue="1"/>

            <f:selectItem itemLabel="2" itemValue="2"/>           

            <a4j:ajax event="change" execute="@this" oncomplete="navigate()"/>

        </h:selectOneMenu>

        <a4j:jsFunction name="navigate" action="yourNavigation rule"/>

Thanks a lot Ibrahim.

It worked for me. but i have another problem.  I have used your solution in a page. Same page has  a4j:poll.    When the poll is happening if I select the drop down its not calling the action method configured in a4j:jsfunction.  But when the poll stops or poll is disabled  it works. Does a4j:poll block other a4j requests. ( They are in diffferent forms). Do I have to use @execute in poll ? or Do ihave to use a4j:region ?

honestly i didn't try this, could you please check @execute, a4j:region and reply back.

I tried  execute=''@none"  it worked.

But there was a side effect. I had a pie chart displayed on page using a javascript on window load. That stopped displaying
