[richfaces-issues] [JBoss JIRA] Commented: (RF-4129) Expanding/collapsing rich:tree nodes from model

[Ingo Jobling (JIRA)]

    [ https://jira.jboss.org/jira/browse/RF-4129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12443269#action_12443269 ] 

Ingo Jobling commented on RF-4129:
----------------------------------

You can do this in Richfaces V3.2.2 using the adviseNodeOpened attribute.  See example [here=>http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4197262#4197262]

The changeExpandListener attribute may also be useful.

> Lets say I bind my Rich Tree to a list of object using the recursiveTreeNodesAdaptor:
> Code:
> <rich:recursiveTreeNodesAdaptor roots="#{rootNodes}" var="node" nodes="#{node.childNodes}">
> <rich:treeNode rendered="#{node.visible}">
>      #{node.name}        						
> </rich:treeNode>
> 	
> with this code:
> rendered="#{node.visible}"
> 	
> I can control if it is visible or not... I would like something similar to control if it is collapsed or not, something like:
> Code:
> collapsed="#{node.collapsed}"
> It would look like this: 
> <rich:recursiveTreeNodesAdaptor roots="#{rootNodes}" var="node" nodes="#{node.childNodes}">
> <rich:treeNode rendered="#{node.visible}" collapsed="#{node.collapsed}">
>      #{node.name}        						
> </rich:treeNode>
> It would be extra-nice if it could propagate back automatically (if a leaf node has collapsed = false, all its parent nodes would be expandend)
