richtree not expanding with special symbols like (&,>)

[ravuri.ravindrababu]

I have problem in <rich:tree> expansion,

If any of the parent node contains

special symbols like (&,>) then the tree expansion is not working....please help me out in solving this problem

how to use rowKeyConverter:

If the <rich:tree> component uses a custom data model, the data model provides unique keys for tree nodes so they can be identified during a client request. The <rich:tree> component can use strings as key values. These strings may contain special characters that are not allowed by browsers, such as the left angle bracket (<) and ampersand (&). To allow these characters in the keys, a row key converter must be provided.

To apply a converter to the <rich:tree> component, define it with the rowKeyConverter attribute.

Hi,

I've tried to reproduce described behaviour, but I haven't been successful. The following code works as expected:

public class Node {

    private List<Node> children;
    private String label;

    public Node(String label, List<Node> children) {
        this.label = label;
        this.children = children;
    }

    public synchronized List<Node> getChildren() {
        if (children == null) {
            children = new ArrayList<Node>();
        }
        return children;
    }

    public String getLabel() {
        return label;
    }

}

@ViewScoped
@ManagedBean
public class TestBean implements Serializable {

    private List<Node> roots;

    @PostConstruct
    public void init() {
        roots = new ArrayList<Node>();
        for (String root : new String[]{"1", "2", "3"}) {
            List<Node> second = new ArrayList<Node>();
            for (String label : new String[]{"A", "B", "C", "D"}) {
                List<Node> third = new ArrayList<Node>();
                for (String l : new String[]{"a", "b", "c", "d"}) {
                    third.add(new Node(label + "-" + l, null));
                }
                second.add(new Node(label, third));
            }
            roots.add(new Node("&Root <" + root +"> & --->", second));
        }
    }

    public List<Node> getRoots() {
        return roots;
    }

}

<h:form>
     <rich:tree toggleType="ajax" var="node">
         <rich:treeModelRecursiveAdaptor roots="#{testBean.roots}" nodes="#{node.children}">
             <rich:treeNode>
                 <h:outputText value="#{node.label}" />
             </rich:treeNode>
         </rich:treeModelRecursiveAdaptor>
     </rich:tree>
 </h:form>

The whole application is available on GitHub: https://github.com/papousek/richfaces-sanbox/tree/thread201994

If the code sample doeasn't solve your problem, could you please provide the minimal code leading to the described behaviour?

Hi Jan Papousek,

I incorporated the code as shared by you but could not execute to see the child nodes on click of the parent node. Surprisingly even I tried with the code base as existing in the showcase http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=treeAdaptors&skin=blueSkybut had the same issue not sure if I am missing something OR going across a wrong path. Below is the exception what I am getting on click of the root node(s). I am using the latest api’s as provided in the 4.2.3 version of jar. Please provide me with your valuable inputs.

I got resolved the above exception by adding

rowKeyConverter="org.richfaces.StringSequenceRowKeyConverter"
