--------------------------------------------------
Great workaround, it works like a charm (but I still would like to be able to
do it the way I propose here)
> Expanding/collapsing rich:tree nodes from model
> -----------------------------------------------
>
> Key: RF-4129
> URL: https://jira.jboss.org/jira/browse/RF-4129
> Project: RichFaces
> Issue Type: Feature Request
> Affects Versions: 3.2.2
> Reporter: Francisco Jose Peredo Noguez
> Assignee: Nick Belaevski
> Fix For: Wishes
>
>
> 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)
