Environment: Tomcat 6.0.x; SEAM 2.0.2.SP1; RichFaces 3.2.2
Task:
Simple richFaces Tree tree.xhtml:
<a4j:outputPanel id="srbTree">
<rich:tree style="width:300px" nodeSelectListener="#{mainTreeBean.processSelection}"
reRender="selectedNode" ajaxSubmitSelection="true" switchType="ajax" value="#{mainTreeBean.treeNode}"
var="item" id="tree" nodeFace="#{item.type}">
.....
Unfortunately, I need to remove a node from the data:
TreeNode treeNode = srbLocationNode.getParent();
TreeNode rootNode = srbWebClient.getSrbWebDomainNode();
if(treeNode != null && rootNode != null)
{
System.out.println("removing srbLocationNode from parent :"+rootNode.hashCode()+ " : "+treeNode.hashCode());
treeNode.removeChild(srbLocationNode);
srbLocationNode.setParent(null);
}
My MainTreeBean.java processSelection:
public void processSelection(NodeSelectedEvent event)
{
HtmlTree tree = (HtmlTree)event.getComponent();
if(tree != null)
{
nodeTitle = SrbWebCommonUtility.getSrbTreeNodeName(tree.getRowData());
String nodeName = "";
TreeNode currentNode = tree.getTreeNode(tree.getRowKey());
if(currentNode != null)
{
if (currentNode.isLeaf())
{
...
I get the following NPE:
java.lang.NullPointerException
org.richfaces.model.TreeDataModelNodeAdaptor$1.getChild(TreeDataModelNodeAdaptor.java:68)
org.richfaces.model.TreeDataModelNodeAdaptor$1.getChild(TreeDataModelNodeAdaptor.java:94)
org.richfaces.model.TreeDataModel.locateTreeNode(TreeDataModel.java:226)
org.richfaces.model.TreeDataModel.locateTreeNode(TreeDataModel.java:187)
Any Help will be dearly appreciated Also looks like somebody already posted this kind of query
https://jira.jboss.org/jira/browse/RF-3802 But no luck there either.
