Unicode problem in rich:tree

[ptdx9]

HI ,I have a problem with rich:tree .when i click on a node with unicode character it throw exception :

WARNING: org.apache.jasper.el.JspELException: /ListFileAndDirectory.jsp(9,0) '#{listFileAndDirectoryBean.processSelection}' java.lang.IllegalStateException: No tree element available or row key not set!

Is this a richfaces bugs ? .Please help me

Here is jsp page code :

<h:outputText id="selectedNode" escape="true" value="Selected Node : #{listFileAndDirectoryBean.nodeTitle}"/>

<rich:tree id="Tree" value="#{listFileAndDirectoryBean.rootNode}" nodeSelectListener="#{listFileAndDirectoryBean.processSelection}"
 reRender="Tree,selectedNode" switchType="ajax" var="item" ajaxKeys="#{null}" ajaxSubmitSelection="true"
 treeNodeVar="treenode" style="width:300px">
 <rich:componentControl event="onClick" for="menu" operation="show"></rich:componentControl>
</rich:tree>


<rich:contextMenu event="oncontextmenu" attached="true" id="menu" submitMode="server">
 <rich:menuItem ajaxSingle="true" value="Download" actionListener="#{listFileAndDirectoryBean.form_download_actionlisener}">
 </rich:menuItem>
</rich:contextMenu>

And a part Bean code with fuction that throw exception :

public void processSelection(NodeSelectedEvent event)
 {
 HtmlTree tree=(HtmlTree)event.getComponent();

 //Error this line
 TreeNode currentNode =(TreeNode) tree.getTreeNode();
 ListRowKey<File> ls=(ListRowKey<File>)tree.getTreeNodeRowKey(currentNode);
 int size= ls.depth();
 if (size>0)
 {
 File f=ls.get(size-1);
 nodeTitle=f.getAbsolutePath();
 if (f.isFile())
 {
 System.out.println("download");
 // downloadFileFromServer(f);
 myfile=f;
 }
 else
 {
 addNodes(currentNode, f.getAbsolutePath());
 }
 }

 }
