Question

I am using richfaces4 and i have a question about rerendering components.

When i rerender my “link_panel” every row of the datatable will rerender its “link_panel”. How can i change this behavior? I would like to rerender just tze current output panel and not for the complete datatable.

greetings, m

<rich:column rendered="#{userBean.renderLinkLinks}">
<f:facet name="header">
    Verlinkt
</f:facet>
<center>
    <a4j:outputPanel id="link_panel">
        <a4j:outputPanel rendered="#{!linkBean.isLinkedWithLerneinheit(lerneinheit)}">
            <h:outputLink > 
                <h:outputText value="Link"/>
                <a4j:ajax event="click" listener="#{linkBean.linkSelectionWithLerneinheit(lerneinheit)}" render="link_panel"/> 
            </h:outputLink>

If you only want to render one link_panel, then you have to have unique id’s for the elements.
