Execute two methods in action in JSF

问题

Is it possible to execute two methods in action of <h:commandButton>?

For example,

<h:commandButton action="#{bean.methodOne();bean.methodTwo();}" />

回答1:

You can use f:actionListener like this.

  <h:commandButton action="#{bean.methodOne();}">
    <f:actionListener binding="#{bean.methodTwo();}" />
  </h:commandButton>

You can add as many f:actionListener elements as you need.

回答2:

Add a methodThree in your bean :

public Object methodThree() {
    methodOne();
    methodTwo();
    return someThing;
}

And call this method from the JSF page.

The accepted answer was close to working for me but the semi-colon was throwing a parse exception. The below code worked:

<h:commandButton>
    <f:actionListener binding="#{bean.methodTwo()}" />
</h:commandButton>
