在JSF2中使用Ajax创建“多米诺骨牌效应”

Question

I'm trying to create a domino like effect when rendering different panelGroups using JSF2 and Ajax. The idé is that depending on the outcome a certain panel will be rendered and shown which in turn renders a third panel, is it possible to create a domino like effect with Ajax to render each panel in succession?

I'm sure I've read about this somewhere, I just can't to find the article again :(

Bind the group components to the view scope and use UIComponent#isRendered() .

<h:panelGroup binding="#{group1}" rendered="#{bean.someCondition}">
    ...
</h:panelGroup>

<h:panelGroup binding="#{group2}" rendered="#{group1.rendered}">
    ...
</h:panelGroup>

<h:panelGroup binding="#{group3}" rendered="#{group2.rendered}">
    ...
</h:panelGroup>
