Hi Cagatay
I tried building a tree component using the code given in the Primefaces "
feature showcase demo".
The tree was successfully built but the various "possible node click events" viz.
onNodeSelect, onNodeExpand & onNodeCollapse were not being fired properly.
The event onNodeExpand was fired once, but after expansion and subsequent collapse of a particular node, the onNodeExpand was not working. And the other events onNodeSelect & onNodeCollapse were not working at all.
I was following these posts' for the past few days and was eagerly waiting to get a solution for the tree node event listeners not working. I downloaded the 0.9.0-SNAPSHOT stuffs and made a .jar. Still the tree events are not working properly. Could you please help me regarding how to trap the tree node events viz. onNodeSelect, onNodeExpand & onNodeCollapse?
Following is the excerpt of the code which I used:
.jsp file
<p:tree value="# {treeBean.model}" toggleMode="async" nodeSelectListener="# {treeBean.onNodeSelect}"
nodeExpandListener="# {treeBean.onNodeExpand}" nodeCollapseListener="# {treeBean.onNodeCollapse}">
</p:tree>
Java Class
@Controller(name="treeBean", scope=Scope.SESSION)
public class TreeBean {
private static final Logger logger = LoggerFactory.getLogger(TreeBean.class);
private TreeNode root;
public TreeBean() {
root = new TreeNode("Root");
TreeNode node0 = new TreeNode("Node 0");
TreeNode node1 = new TreeNode("Node 1");
TreeNode node2 = new TreeNode("Node 2");
TreeNode node00 = new TreeNode("Node 0.0");
TreeNode node01 = new TreeNode("Node 0.1");
TreeNode node10 = new TreeNode("Node 1.0");
TreeNode node11 = new TreeNode("Node 1.1");
node00.addChild(new TreeNode("Node 0.0.0"));
node00.addChild(new TreeNode("Node 0.0.1"));
node01.addChild(new TreeNode("Node 0.1.0"));
node10.addChild(new TreeNode("Node 1.0.0"));
node0.addChild(node00);
node0.addChild(node01);
node1.addChild(node10);
node1.addChild(node11);
root.addChild(node0);
root.addChild(node1);
root.addChild(node2);
}
public TreeNode getModel() {
return root;
}
public void onNodeSelect(NodeSelectEvent event) {
String node = event.getTreeNode().getData().toString();
System.out.println("Selected:" + node);
}
public void onNodeExpand(NodeExpandEvent event) {
String node = event.getTreeNode().getData().toString();
System.out.println("Expanded:" + node);
}
public void onNodeCollapse(NodeCollapseEvent event) {
String node = event.getTreeNode().getData().toString();
System.out.println("Collapsed:" + node);
}
}
Waiting for an early reply from you, since I am stuck very badly
Thanks in advance!!
