Selection in Tree

[ebariaux]

I have a rich:tree displaying some information on the left of the page and some detail about the selected item displayed on the right of the page.

Using a nodeSelectListener binding, I store the row key of the selected object whenever an element is selected in the tree.

I also have the possibility to add and delete elements in the tree.

Let's say I have 3 elements in the tree, the last one is selected and I delete it, the tree still remembers that the 3rd element is selected (even if there is only 2 elements in the tree).
So now if I had a new element, it becomes the 3rd one and is automatically selected.

What I would prefer is that when I delete the 3rd element, the tree "looses" its selection, or that there is a method I can call from my backing bean to reset the selection on the tree.

In fact, that last option would be useful in several cases.
Is there a way to do that?


Thanks,
Eric

Hi,

maybe using a StateAdvisor would solve the problem !?

Hi all.
I tired the following code:

TreeState state = (TreeState) tree.getComponentState();
state.setSelected(null);

It works fine for me, I use jsf 1.1 (sum impl) and richfaces 3.1.0
