Rich Tree: Opening/Collapsing a Node from Model

[luxspes]

Hi!

Lets say I bind my Rich Tree to a list of object using the recursiveTreeNodesAdaptor:

<rich:recursiveTreeNodesAdaptor roots="#{rootNodes}" var="node" nodes="#{node.childNodes}">
<rich:treeNode rendered="#{node.visible}">
 #{node.name}
</rich:treeNode>

Is it possible to open a node from model? I mean, with

rendered="#{node.visible}"

I can control if it is visible or not... Is there something similar to control if it is collapsed or not? something like:

collapsed="#{node.collapsed}"

I can not find any example of a way to do that...

Since I think this is not possible currently with RichFaces, I posted a feature request: RF-4129

You can do this in Richfaces V3.2.2 using the adviseNodeOpened property.

For example, the following code opens all nodes at level 3 or less:

<rich:tree adviseNodeOpened="#{treeController.adviseNodeOpened}" />

In the backing bean:

 public Boolean adviseNodeOpened(UITree tree) {
 Object key = tree.getRowKey();
 TreeRowKey treeRowKey = (TreeRowKey) key;
 if (treeRowKey == null || treeRowKey.depth() <= 3) {
 return Boolean.TRUE;
 }

Yes, you are right, it works great... (But I still would like to be able to do it as I propose in RF-4129, I think it would be more intuitive that way)

You can use one of the 3 walk methods of org.richfaces.component.UITree to expand a node from the service-layer of your jsf-application. Have a look at waffels blog:
