Question

Richfaces modal panel text display problem

Asked by: qrahman

I am new to JSF/Richfaces. I have a a4j:commandButton, clicking on which brings up a modal panel. I am setting 3 properties in the backing bean using a4j:actionparam within the a4j:commandButton code block. My intention is that when the button is clicked, modal window code will read these properties from the backing bean and display message appropriately. Problem: the moment the page that has the button is loaded, the getters (value is null at this point) in modal panel are already being invoked even though I haven't clicked on the button yet. The values being set using actionparam are being completely ignored. If I am not very clear describing the problem, please ask me questions. 

-----------------
Button code
-----------------
 
<a4j:commandButton value="Reconcile"
                   disabled="#{ViewResult.reconciliationNotAllowed}"
                   oncomplete="javascript:Richfaces.showModalPanel('confirmPanel');">
      <a4j:actionparam name="contentStatusCS" value="#{contentDetail.contentStatusCS}" assignTo="#{ViewResultDetail.contentStatusCS}"></a4j:actionparam>
     <a4j:actionparam name="contentName" value="#{contentDetail.contentName}" assignTo="#{ViewResultDetail.contentName}"></a4j:actionparam>
     <a4j:actionparam name="moduleName" value="#{contentDetail.moduleName}" assignTo="#{ViewResultDetail.moduleName}"></a4j:actionparam>
</a4j:commandButton>
 
--------------------------------------------------------------
Modal Panel (note the getters in the message body)
---------------------------------------------------------------
 
 <rich:modalPanel id="confirmPanel" autosized="false" keepVisualState="false" width="400" height="150">
    <f:facet name="header">
       <h:outputText value="Confirm Delete" />
    </f:facet>
    <h:panelGroup layout="block" styleClass="scrolls">
       <h:form>
          <center><rich:spacer height="20" /> 
		<h:panelGrid columns="1">
                  <h:outputText value="Do you want to delete the #{ViewResultDetail.contentStatusCS} content #{ViewResultDetail.contentName} from content store [name]?" />
                    </h:panelGrid> <rich:spacer height="30" /> <h:panelGrid columns="2">
                                    <a4j:commandButton value="OK" onclick="Richfaces.hideModalPanel('confirmPanel');" />
                                    <a4j:commandButton value="Cancel" onclick="Richfaces.hideModalPanel('confirmPanel');" />
                     </h:panelGrid>
          </center>
       </h:form>
    </h:panelGroup>
</rich:modalPanel>

I think you are complicating unnecessary with use of <a4j:actionparam>?
I suggest you to use "action" param of the commandButton to call the method in the backing bean and there set all values you want shown in Modal Panel. Leave onComplete as it is and call reRender="confirmPanel", like this:

<a4j:commandButton value="Reconcile" disabled="#{ViewResult.reconciliationNotAllowed}" oncomplete="javascript:Richfaces.showModalPanel('confirmPanel');" reRender="confirmPanel" action="#{ViewResult.onShowModal}">

Do the same (use action to call managed bean method) with Command buttons inside Modal panel.


I hope this helps,

Not sure how I could make this work without passing params because backing bean does not any knowledge of the user selection, however your post made me realize that I needed to reRender the modal panel to make it work. Once I reRendered the modal window, it's working as expected.Thanks for your help.

Bind the field value to the property in backing bean so you can easily get it in your method.

Aha, you mean user selection in the modal panel?
Well, same as you do in the commandButton which you use to raise modalPanel, use action or actionListener on both Ok and Cancel commandButtons to call different methods of backing bean.
