<rich:tree> NullPointerException on row click
I have a <rich:tree> im using for navigation. When I click on a row I get a NullPointerException:

I have no clue what is causing this error
Here is my code:
xhtml:
<h:form id="richSideBarForm" >
<r:tree id="richTreeBar" value="#{richTree.rootNode}" var="node" toggleType="client" selectionType="ajax"
iconExpanded="/resources/images/FolderOpen_web.png" iconCollapsed="/resources/images/FolderClosed_web.png"
iconLeaf="/resources/images/Worksheet_web_mini.png" selectionChangeListener="#{richTree.processTreeSelectionChange}">
<r:treeNode id="rootNode" >
<h:outputText id="rootNodeOutput" value="#{node}" />
</r:treeNode>
<r:treeNode id="leafNode" >
<h:outputText id="leafNodeOutput" value="#{node}" />
</r:treeNode>
</r:tree>
</h:form>
BackingBean:
public class RichTree implements Serializable, TreeSelectionChangeListener{
private TreeNode rootNode;
private UITree treeBinding;
public RichTree() {
rootNode = new TreeNodeImpl();
loadTree();
}
/**
* @return the rootNode
*/
public TreeNode getRootNode() {
return rootNode;
}
public void setRootNode(TreeNode rootNode) {
this.rootNode = rootNode;
}
private void loadTree() {
AGOTreeNode summaryNode = new AGOTreeNode();
summaryNode.setLabel("0000000001");
getRootNode().addChild(0, summaryNode);
AGOTreeNode childNode = new AGOTreeNode();
childNode.setLabel("Node1");
summaryNode.addChild(0, childNode);
childNode = new AGOTreeNode();
childNode.setLabel("node2");
summaryNode.addChild(1, childNode);
}
@Override
public void processTreeSelectionChange(TreeSelectionChangeEvent tsce) throws AbortProcessingException {
List<Object> selection = new ArrayList<Object>(tsce.getNewSelection());
Object currentSelectionKey = selection.get(0);
UITree tree = (UITree) tsce.getSource();
tree.setRowKey(currentSelectionKey);
AGOTreeNode node = (AGOTreeNode) tree.getRowData();
String label= node.getLabel();
FacesContext fc = FacesContext.getCurrentInstance();
fc.getApplication().getNavigationHandler().handleNavigation(fc, "", label);
}
AGOTreeNode extends TreeNodeImpl and adds a few feilds and also overwrites the toString method.
Any Help is greatly appreciated!
---EDIT---
I dont know if it is important but the navigation tree is part of one xhtml file which is being included in my template using a <ui:include> tag
