Question

Using JSF2 and richfaces 4.

I have two regions in my form with multiple regions. I want to call render for another region. How can I do it?

<h:form>
    <a4j:region id="rg_1">
        <h:inputText id="field1" value="#{bean.field1}"/>   
    </a4j:region>
    <a4j:region id="rg_2">
        <a4j:commandLink action="#{mybean.resetBean} render="region1" />
    </a4j:region>
</h:form>

Answer 1

h:commandLink does not have render attribute , f:ajax does…

If you want to re render rg_1 from within rg_2 without page refresh (ajax)

do the following

<a4j:region id="rg_2">
    <a4j:commandLink action="#{mybean.resetBean}" render="rg_1"/>
</a4j:region>

also make sure that mybean.resetBean method is a void method or returns null
