Tree Ajax select event only fires with selection Node, why?

[djmj]

I have a Tree where the child's of a node are loaded if that node is selected. (Reduce remote database hits.)

Code: Select all

<p:ajax event="select" listener="{bean.listener}"/>

Fires only if I also add a selected TreeNode Object to my bean.
But what if I don't need that Node at all. (If Tree is just presenting data)

Is it by design? Since it is not mentioned in the documentation.

(Did not tested it with datatable but I assume its the same)


For that case something like an uninitialized icon/flag would be cool.
