Rich suggestionbox issue with f:setPropertyActionListener

[marczeeee]

Hello,

I'm trying to get a suggestionbox to work with f:setPropertyActionListener with no success. I'm doing it as it should be done, using the actionListener in an a4j:support element listening to the onselect event. But anyhow I set the value property of the actionListener, I always got a null for it at the end. I read about this problem in earlier posts, but as far as I saw this was a bug and got fixed around Richfaces 3.1.x. I'm using 3.3.3.Final now. Could this a bug again or could this be a problem somewhere in my enviroment? I'm developing portlets under Liferay with Richfaces.

Thanks in advance,

Marton

Please, provide a sample of your code.

This is the code used in portlets. We just include it where it's needed.

{code:xml}
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
          xmlns:ui="http://java.sun.com/jsf/facelets"
          xmlns:h="http://java.sun.com/jsf/html"
          xmlns:f="http://java.sun.com/jsf/core"
          xmlns:a4j="http://richfaces.org/a4j"
          xmlns:rich="http://richfaces.org/rich">
          <h:panelGroup>
             <a4j:region id="region">
                  <table>
                       <tr>
                            <td><h:outputText value="*" rendered="#{required}" /></td>
                            <td><h:outputLabel for="#{componentId}" value="#{label}" title="#{title}" /></td>
                            <td><h:inputText id="#{componentId}"
                                      required="#{required and !readonly}" readonly="#{readonly}"
                                         maxlength="#{maximum}" title="#{title}" >
                                </h:inputText>
                                <rich:suggestionbox for="#{componentId}" var="userActor"
                                        suggestionAction="#{suggestionBean.autoCompleteActor}" width="350"
                                        minChars="3" nothingLabel="#{msgCommon['noMatchesFound']}"
                                        ignoreDupResponses="true">
                                        <h:column>
                                          <h:outputText value="#{userActor.value}" />
                                        </h:column>
                                        <h:column>
                                          <h:outputText value="#{userActor.label}" />
                                        </h:column>
                                        <a4j:support event="onselect" ajaxSingle="true">
                                          <f:setPropertyActionListener target="#{targetProperty}" value="#{userActor.value}" />
                                     </a4j:support>
                                 </rich:suggestionbox></td>
                             <td width="28">
                                  <a4j:status for="region">
                                          <f:facet name="start">
                                            <h:graphicImage value="/images/actions/suggestionStatus.gif"
                                                 style="padding-left: 3px;" />
                                          </f:facet>
                                </a4j:status>
                             </td>
                       </tr>
                  </table>
             </a4j:region>
          </h:panelGroup> 
</ui:composition>
{code}

The problem is that the #{userActor.value} expression expressed to a null value when the target property's setter is called. But the value is valid and not null as it is displayed by the suggestionbox as a result.

Please try a4j:actionparam instead of f:setPropertyActionListener

[marczeeee]

I changed the setPropertyActionListener to a4j:actionparam, but no success. The property's setter method didn't even get called. Used it the following way:

{code:xml}<a4j:actionparam name="userActor" value="#{userActor.value}" assignTo="#{targetProperty}"/>{code}

Tried to set the surrounding a4j:support tag's ajaxSingle and immediate attributes, but nothing changed.

Some more info about a4j:actionparam I found out: tried to use it without the assignTo parameter to set a request parameter value and process that with a method in my backing bean. If I use a static value as value parameter of the a4j:actionparam it works properly. But if I put an EL expression as value I only get an empty string as request parameter value.

Ok, I found the solution: we had the following context-param in our web.xml:

{code:xml}
<context-param>
     <param-name>facelets.BUILD_BEFORE_RESTORE</param-name>
     <param-value>true</param-value>
</context-param>{code}

After deleting this, everything works as expected.
