People,
I have this code:

<rich:tabPanel id="tabPanel" selectedTab="tab1" immediate="true" switchType="ajax">
<rich:tab label="Tab1" name="tab1" >
 <a4j:form requestDelay="20" ignoreDupResponses="true">
 ...
 <a4j:commandButton action="#{bean.acionExec}" value="go">
 </a4j:form>
</rich:tab>
<rich:tab label="Tab2" name="tab2" >
 tab 2
</rich:tab>
/rich:tabPanel>

How can I change tab active when I click on "go" button ?

If tabPanel is "client" I put this javascript on onclick button event: "RichFaces.switchTab('tabPanel','mant','manter');"

but how do I do when tabPanel is ajax type?
