a4j:commandButton disabled delay oncomplete - How?

[nt2005]

Hello Community,

I am using Richfaces 3.3.3 and I like to add a delay to a button after the request is finish. I am not very good in javascript but I tried something like this:

<a4j:commandButton value="Start" action="#{foo.start}" reRender="panel"
 onclick="this.disabled=true" oncomplete="setTimeout('this.disabled=false;',3500)">
</a4j:commandButton>

It does not work. the button never get enable again...

What would best:

rerender when oncomplete is called and after 3-4 secounds the button should enable again. Anyone have an idea?

Thanks in advance.

<a4j:commandButton id="start" value="Start"

                    action="#{foo.start}"

                    reRender="panel"

                    onclick="this.disabled=true" oncomplete="enableStartButton()">

</a4j:commandButton>

<a4j:jsFunction name="enableStartButton" ajaxSingle="true" requestDelay="3000" reRender="start"/>

Got it. Thanks anyway.
