Error during adding new node to the tree

[bartman12]

Hi,
I'm trying to add a new node to the tree.I have made a commundButton which is responsible for it.
When I add new node to the nodes which I have created in my java constructor everything is ok, but when I add a node and then I add a node to the one I have created before StuckTrace appears.
This is my xhtml code:

Code: Select all

<h:form>  
   <p:commandButton value="Add node" update="treeSingle" actionListener="#{treeBean.addNode}" ></p:commandButton>
  
   <p:tree id="treeSingle" value="#{treeBean.root}" var="node"  
            selectionMode="single"  
            selection="#{treeBean.selectedNode}">  
        <p:treeNode>  
            <h:outputText value="#{node}" />  
        </p:treeNode>  
    </p:tree>  
  
</h:form>  

And Java class:

Code: Select all

	public TreeBean() {
		root = new DefaultTreeNode("Root", null);
		TreeNode node0 = new DefaultTreeNode("Node 0", root);
		TreeNode node1 = new DefaultTreeNode("Node 1", root);
		TreeNode node100 = new DefaultTreeNode("Node 1.0.0", node10);
	}

	public void addNode() {
		if (selectedNode != null) {
			TreeNode node = node=new DefaultTreeNode("New node", selectedNode);
			
		}
	}

Error message:

Code: Select all

i confirm this issue. other users report this problem too:

after changing a tree structure programatically, exceptions like this occur if e.g. selecting a node:

Code: Select all

INFO: java.lang.IndexOutOfBoundsException: Index: 1, Size: 0
java.lang.IndexOutOfBoundsException: Index: 1, Size: 0
        at java.util.ArrayList.RangeCheck(ArrayList.java:547)

        at org.primefaces.component.api.UITree.findTreeNode(UITree.java:112)

hint for others running into this problem: as a temporary workaround for node selection i use a node label span onclick that triggers a prepared RemoteCommand with parameter. thus i can disable node selection and problem is challenged for now.
