nodeSelectListener
I'm having a real problem getting a nodeSelectListener to work... it just will not respond ehere is the page code:
<h:panelGrid columns="2" width="100%">
<rich:tree style="width:300px" switchType="client"
value="#{BillExplosionBean.rootNode}" var="item" ajaxKeys="#{null}">
<rich:treeNode nodeSelectListener="#{BillExplosionBean.processSelection}"
reRender="selectedNode" ajaxSubmitSelection="true" >
<h:outputText value="#{item.seq}" />
<h:outputText value=": " />
<h:outputText value="#{item.part}" />
<h:outputText value=": " />
<h:outputText value="#{item.usage}" />
</rich:treeNode>
</rich:tree>
<h:outputText escape="false" value="Selected Node: #{BillExplosionBean.nodeTitle}" id="selectedNode" />
</h:panelGrid>
Here is the bean code
public void retrieveBill(String parent){
rootNode = new TreeNodeImpl();
Bill bill = new Bill();
bill.setPart(parent);
TreeNode parentNode = new TreeNodeImpl();
parentNode.setData(bill);
rootNode.addChild(bill, parentNode);
List<Bill> bills = dao.retrieveBillByParent(parent);
walkTree(parentNode, bills);
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
HttpServletRequest httpReq = (HttpServletRequest) ec.getRequest();
httpReq.setAttribute(AppConstants.BILL_EXPLOSION_BEAN, this);
}
private void walkTree(TreeNode parent, List<Bill> bills){
for (Bill bill : bills){
// do some processing to build the tree
TreeNodeImpl nodeImpl = new TreeNodeImpl();
nodeImpl.setData(bill);
parent.addChild(bill, nodeImpl);
// uncomment to output to System.out
// get the subordinate parts
List<Bill> childBills = dao.retrieveBillByParent(bill.getPart());
walkTree(nodeImpl, childBills);
}
}
public void processSelection(NodeSelectedEvent event) {
HtmlTree tree = (HtmlTree) event.getComponent();
nodeTitle = (String) tree.getRowData();
selectedNodeChildren.clear();
TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());
if (currentNode.isLeaf()){
selectedNodeChildren.add((String)currentNode.getData());
}else
{
Iterator<Map.Entry<Object, TreeNode>> it = currentNode.getChildren();
while (it!=null &&it.hasNext()) {
Map.Entry<Object, TreeNode> entry = it.next();
selectedNodeChildren.add(entry.getValue().getData().toString());
}
}
}
The tree displays nicely on the page and will expand/collapse but selecting a node does not call the processSelection(NodeSelectedEvent event) method and I am at a loss as to why.
Anyone?
