I need to use the a4j:commandButton instead of h:commandButton because of its reRender option.

When I’m using h:commandButton, it works fine (but off course without reRender): 

<h:commandButton id="save" action="#{bean.save}" value="#{conf.buttonSave}"/>

And the same thing using doesn’t (action isn’t started even withour reRender option):

<a4j:commandButton id="save" action="#{bean.save}" value="#{conf.buttonSave}"/>

I’ve also tried:

<h:commandButton id="save" action="#{bean.save}" value="#{conf.buttonSave}">
 <a4j:ajax event="click" reRender="table" />
</h:commandButton>

But if I add a4j:ajax it the same problem as a4j:commandButton, action is not started.

Could you help me?

    You tagged this JSF 2.0. So you’re using JSF 2.0. Just use the JSF 2.0 builtin <f:ajax> tag.

    <h:commandButton id="save" action="#{bean.save}" value="#{conf.buttonSave}">
    <f:ajax render="table" />
</h:commandButton>

    Note that <h:dataTable id="table"> must be within the same <h:form> the above way. Otherwise you need render=":table" instead. Also note that you must have a <h:head> instead of <head> in the template in order to get all necessary JavaScripts auto-included.
