Rich Tree Expand node

[mattc1]

We would like to be able to expand a node in a rich tree using javascript. Is there an example of this? Also is there a way to get the row key of a node in the tree via javascript?

Hmmm ... I think this is (currently) not possible.

For such client side code the whole tree have to stay on the client (switchType="client").

Please describe more details. What do you want to do?

We have a tree with multiple node types. Some nodes we want to toggle on click but not select the node and other nodes we only want to toggle by clicking the arrow. Basically some nodes we want to behave as if the expand arrow is clicked when the node text is clicked.

I came up with this script

function setNodeToggle(e) {
 var elt = Event.element(e);

 var treeItem = Tree.Item.findComponent(elt);
 if (treeItem.isCollapsed())
 treeItem.expand();
 else
 treeItem.collapse();
}

That gets called by changing my rich:treeNode to

<rich:treeNode type="contactfolder" onclick="setNodeToggle(event);" onselected="return false;">

This appears to work. Does it look like a valid approach?

Looks good ... you can define different behaviors for different node-types.

Have a look into my last blog about "customized rich tree"
