JSF multiple actionListeners called in order with update

Question

Using JSF 2 I understand I can call multiple actionListeners as such:

<h:commandButton value="Action">
    <f:actionListener binding="#{myBean.actionOne()}" />
    <f:actionListener binding="#{myBean.actionTwo()}" />
</h:commandButton>

However, I would like to call one actionListener and perform an update to the @form. Once this first call and update are complete call a 2nd actionListener and perform another update. Is this possible?

Answer 1

Yes. With <h:commandScript>.

<h:form>
    ...
    <h:commandButton value="Action" action="#{myBean.actionOne}">
        <f:ajax render="@form" onevent="function(data) {
            if (data.status === 'success') actionTwo();
        }"/>
    </h:commandButton>
    <h:commandScript name="actionTwo" action="#{myBean.actionTwo}"
         render="...">
    </h:commandScript>
</h:form>

In case you're not on JSF 2.3 yet, see How to invoke a JSF managed bean on a HTML DOM event using native JavaScript? for alternatives.

In case you're using PrimeFaces (given away by your question history confirms this and using the term 'update' instead of 'render'), the <p:remoteCommand> is the equivalent.

<h:form>
    ...
    <p:commandButton value="Action" action="#{myBean.actionOne}"
         update="@form" oncomplete="actionTwo()">
    </p:commandButton>
    <p:remoteCommand name="actionTwo" action="#{myBean.actionTwo}"
         update="...">
    </p:remoteCommand>
</h:form>
