Dynamically passing bean to rich:popupPanel

Question

I have a base class, which is normal Java class. Three subclasses extend it which are @ViewScoped beans. There's a facelet using a dynamic variable. I have three xhtml pages which use this facelets with the three beans viz. bean1, bean2 and bean3 which are dynamically included in a rich:tab component on a main page. So far so good. But on every page there are a few popups which should refer to the current bean. And since those popups need form tag inside them, I have included them outside the main page's form tags in order to avoid nested form tags. Now I want the popup to refer to current bean (bean1, bean2 or bean3, depending upon from where the popup is called) in question. How do I achieve this?

Answer 1

Try something like this:

1. Add a new bean (popupBean) that will contain reference to current bean in popup.

2. Add an action that will set needed bean as property of popupBean. Example:

   <h:commandLink>
       <a4j:ajax render="myPopup"/>
       <f:setPropertyActionListener target="#{popupBean.currentBean}" value="#{bean1}"/>
       <h:outputText value="Click ME!"/>
   </h:commandLink>
   

3. Use show attribute of rich:popupPanel to show the popup:

   <rich:popupPanel id="myPopup" modal="true" width="600" moveable="true" 
           show="#{not empty popupBean.currentBean}" onmaskclick="#{rich:component('myPopup')}.hide();" autosized="true">
       <f:facet name="header"><h:outputText value="Cool popup!"/></f:facet>
       <h:panelGrid style="margin: 0">
           <h:panelGroup style="max-height: 400px;overflow-y: auto;" layout="block">
               <h:outputText value="#{popupBean.currentBean.myBeanProperty}"/>
           </h:panelGroup>
           <h:button value="Close" onclick="#{rich:component('myPopup')}.hide();return false;"/>
       </h:panelGrid>
   </rich:popupPanel>
