rich:tree node selection problem..

kepler Mar 23, 2010 4:59 AM

Hey everyone, i have a problem with rich tree component.

I am dynamicaly creating a treeNode and adding to selected node. everything looks and works fine until i select some older nodes, i get an illegal state exception (full trace below..)

thx in advance..

here is my xhtml tree :

         <rich:tree id="treeId" switchType="client"
                nodeFace="#{item.type}"
                nodeSelectListener="#{viewBean.processParentSelection}"
                ajaxSubmitSelection="true"
                value="#{viewBean.dummyTreeNode}" var="item">
                <rich:treeNode type="TYPE1"
                    icon="/images/puzzle1.png" reRender="treeId"
                    iconLeaf="/images/puzzle1.png">
                    <h:outputText value="#{item.info}" />
                </rich:treeNode>
            </rich:tree>

here is my java code to create and insert new nodes..

void addNode(ViewBean viewBean) {

        TreeNode<TreeNodeData> parentNode = viewBean.getSelectedTreeNode();
        TreeNodeData parentTreeNodeData = parentNode.getData();    // custom node data object.
        Set<TreeNodeData> set = parentTreeNodeData.getSubSet();
        TreeNodeData childTreeNodeData = new TreeNodeData();
        TreeNode<TreeNodeData> cihldNode = new TreeNodeImpl<TreeNodeData>();
        childTreeNodeData.setSomeValue("..");
        set.add(childTreeNodeData);
        cihldNode.setData(childTreeNodeData);
        cihldNode.setParent(parentNode);
        parentNode.addChild(childTreeNodeData, cihldNode);

}

Full stacktrace:

java.lang.IllegalStateException: No tree element available or row key not set!

Hi,

This exception happens when tree component cannot find requested node in the model. So the first thing to check is whether the model is in synchronization with the view, e.g.:

- Model is correctly recreated between requests
- Modified nodes are updated (re-rendered) in the view

Nick, thx for the info,
i think you have a point about unsync.ed tree state. the error especially occurs after i select several nodes (thus rerendering entiire tree several times)..
i may try to update the model every time i select a node or partially render the tree
thx again

problem solved. i am reRendering treeNodes every time a node selected, this is the reason of unsyncrhnzd model-view state. i removed the reRender statement and tree is okay now, gonna live
