    Rich suggestionbox issue with f:setPropertyActionListener

    Marton Horvath Newbie

      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

            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

                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.
