When is TreeStateAdvisor called?

anders.norgaard Sep 19, 2008 7:33 AM

I would like to have my tree expanded depending on the state of comboboxes elsewhere in the gui. So I have implemented a TreeStateAdvisor - and declared it with the stateAdvisor attribute like this:

<rich:tree rendered="#{cpemanager.hasDSL()}" value="#{cpemanager.propertiesTree()}"
 var="item" nodeFace="#{item.type()}" id="conftree" stateAdvisor="#{cpemanager.advisorImpl}">

But the methods "adviseNodeOpened" or "adviseNodeSelected" are never called. How do I actually get the tree to check which node should be expanded?

Anders,

These methods are called when tree component is being rendered for the nodes processed (i.e. for ajax tree only the re-rendered nodes will ask for advise but not all tree nodes).

Ah, ok. Is there any way I can force a re-render of the complete tree then? (so that all nodes will ask for advice)

Thanks

Anders,

You can wrap tree in output panel and re-render it or bind ajaxKeys to the singleton set containing null value.

Thanks for the tips. Actually I just needed to start thinking :)

and set the

reRender="mytree"

on some of my gui-elements.

Thanks again
