rich tree not working after

[arul002]

Hi,

I am new to richfaces and tried using the tree in this livedemo link - http://ludvigsens.net/richfaces-3.3.2/richfaces/tree.jsf?tab=model&cid=107033

This tree is working fine when switchType is client. If you change the switchType to ajax/server, expanding and collapsing a tree node is not working after selecting one of its child node.

I searched for this issue in the forum but couldnt able to find one except this http://community.jboss.org/message/35257#35257 but no asolution is there.

Anyone already faced this issue? I am using richfaces 3.3.1.GA version in my project. Please help.

All the source files are available in the richfaces livedemo http://ludvigsens.net/richfaces-3.3.2/richfaces/tree.jsf?tab=model&cid=107033.

Still here it is,

          <h:outputText escape="false" value="Selected Node: #{simpleTreeBean.nodeTitle}" id="selectedNode" />
       </h:panelGrid>
      </h:form>
</ui:composition>

Managed bean - simpleTreeBean is also available in the same livedemo page.

I tried that on my local demo and works fine. Please consider checking on latest version.

Hi,

The issue is with tree.getRowData() in processSelection method. It gives IllegalStateException whenever I expand/collapse a node after selecting one of its child node. There must be a better solution but if I just catch this exception-do nothing, then everything's working fine.

public void processSelection(NodeSelectedEvent event) {

        HtmlTree tree = (HtmlTree) event.getComponent();

        Object rowKey = tree.getRowKey();

//        try {

nodeTitle = (String) tree.getRowData(rowKey);

selectedNodeChildren.clear();

TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());

/*} catch (IllegalStateException e) {

e.printStackTrace();

}*/

public void processSelection(NodeSelectedEvent event) {

             HtmlTree tree = (HtmlTree) event.getComponent();

             Object rowKey = tree.getRowKey();

             try {

                nodeTitle = (String) tree.getRowData(rowKey);

                selectedNodeChildren.clear();

                TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());

           } catch (IllegalStateException e) {

                e.printStackTrace();

           }

}

Could you please tell me the version of richfaces you tried. I tried it in 3.3.3.Final but still the problem exists - java.lang.IllegalStateException - No tree element available or row key not set!

Yup, I could see the exception now also. But it not prevents the tree from working in my case, so I not found from the beginning. And it seems - catching the exception is the only way. It's looks like an issue in component but as we have no plans for 3.3.x branch releases - please use workaround.
