rich:tree and JSF lifecycle

[jsoye]

Hi all,

I'm having a problem refreshing a display which uses a rich:tree for navigation and

a dynamically generated HtmlPanelGrid (depending on the tree node selected). It always

displays the previous result (as opposed to the last one selected). I've tried using

immediate="true" but the same behaviour results.

My code is

{code}

        <rich:tree id="myTree" var="node" nodeType="#{node.type}" value="#{myBean.treeNodes}"

                   toggleType="client" selectionType="ajax" immediate="true">

            <rich:treeNode type="CATEGORY_1" iconExpanded="...png" iconCollapsed="...png">

                <a4j:outputPanel>

                    <h:outputText value="#{node}" />

                    <a4j:ajax render="gridPanel" event="click"  immediate="true" listener="#{myBean.updateSelectedNode(node)}"/>

                </a4j:outputPanel>               

            </rich:treeNode>

            <rich:treeNode type="CATEGORY_2" iconExpanded="...png" iconCollapsed="...png">

                <h:outputText value="#{node}" />

            </rich:treeNode>

        </rich:tree>

        ...       

        <h:panelGroup id="gridPanel" layout="block">

            <h:panelGrid id="displayGrid" binding="#{dynamicComponentBean.displayGrid}" columns="2" />

        </h:panelGroup>      

{code}

I also used a different selection listener style, i.e.

{code}

            <rich:treeSelectionChangeListener for="myTree" listener="#{myBean.nodeTreeSelectionChanged}"/>

{code}

but the same problem occurs - I can't get the panelGroup to refresh immediately with the panelGrid corresponding to the node selected.

If anyone could shed some light I'd be very grateful. Thanks.

Sorry,

I should have added that I'm using

• Richfaces 4.1.0.20110805-M1
• JBoss AS 7 Final
• Seam 3.0.0.Final

Gotcha. Took a break for a few days and moved onto something else. Returned afresh (not really!) and tried a slight variation. Works this way.

Here's my approach for those interested. Might save you from the headaches it caused me.

        <rich:tree id="myTree" var="node" nodeType="#{node.type}" value="#{myBean.treeNodes}"

                   toggleType="client" selectionType="ajax">

            <rich:treeSelectionChangeListener for="myTree" listener="{myBean.nodeTreeSelectionChanged}"/>

            <rich:treeNode type="CATEGORY_1" iconExpanded="...png" iconCollapsed="...png">

                <a4j:outputPanel>

                    <h:outputText value="#{node}" />

                    <a4j:ajax event="click" render="gridPanel"/>

                </a4j:outputPanel>

            </rich:treeNode>

            <rich:treeNode type="CATEGORY_2" iconExpanded="...png" iconCollapsed="...png">

                <a4j:outputPanel>

                    <h:outputText value="#{node}" />

                    <a4j:ajax event="click" render="gridPanel"/>

                </a4j:outputPanel>

            </rich:treeNode>

        </rich:tree>

I thought I had tried this approach before, but obviously I missed something. C'est la vie.
