rich:tree and nodeSelectListener

margotmedia Aug 5, 2009 3:26 PM

Hi!

I am using rich:tree in my application and it works fine except the nodeSelectListener (even it should be the expected behaviour).

When a node is selected, my selectListener is called correctly. Now a user can click an a4j:commandButton in my application. This command button executes some update action on the form. Now I want, that the selected node can be selected a second time. But, when the user clicks the selected node, the selectListener isn't called.

May be it is the expected behaviour, but i need this feature like I explained above. It's very important for the application.

Does anybody know a workaround for this scenario?

Thank you very much!

regards,
margotmedia.

fyi: I tried also rerendering the tree component, but despite the rerendering the node is still selected and when clicking on the node the selectListener isn't called.

I looked in the javadoc, but couldn't find a method for setting or getting the selected node. Did I miss anything?

Thanks!

use tree state advisors in order to select/deselect/expand/collapse nodes between requests.

Thank you for your reply! These methods are for sure very useful. But I didn't find good documentations or examples, so I wan't able to use them.

However I found out how to solve my problem. Now I using the componentState attribute of the tree. With the componentState in the backing bean, I can easily change the state at any time I want and then reRender the tree.
