rich:treeNode / How to disable treeNodes in a rich:tree

[bm97]

How can i disable treeNodes in the rich:tree?

Background information: In your app the tree defines which detailview is selected. And there is the requirement, that treeNodes with "no" content on the detailview, should be disabled.

a) So how can a treeNode be disabled OR
b) how it is possible to prevent selections on a treeNode?


Thank you! Greetings, Ben

 <rich:tree id= "tree"
 switchType= "ajax"
 nodeSelectListener= "#{manager.onSelect}"
 ajaxSubmitSelection= "true"
 toggleOnClick= "false"
 immediate= "true"
 showConnectingLines= "false"
 disableKeyboardNavigation="true"
 preserveModel= "none"
 reRender= "fooBar"
 >
 <rich:recursiveTreeNodesAdaptor roots="#{manager.roots}" var="item" nodes="#{item.children}" >
 <rich:treeNode>
 <h:outputText value="#{item.id} - #{item.name}" />
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
 </rich:tree>

Could it be done with a customized renderer?

In general you could introduce some special type for example which will be added to nodes object which has no details during building tree structure. And add separate tree node to tree to define needed representation for them and turn off selection and submits from them.

Thanks Ilya. It was easier than expected.

SOLUTION:

Use onselected="return false;" for the disabled node.

 <rich:tree id= "tree"
 switchType= "ajax"
 nodeSelectListener= "#{manager.onSelect}"
 ajaxSubmitSelection= "true"
 toggleOnClick= "false"
 immediate= "true"
 showConnectingLines= "false"
 disableKeyboardNavigation="true"
 preserveModel= "none"
 reRender= "fooBar"
 >
 <rich:recursiveTreeNodesAdaptor roots="#{manager.roots}" var="item" nodes="#{item.children}" >
 <rich:treeNode onselected="" rendered="#{item.enabled}">
 <h:outputText value="#{item.id} - #{item.name}" />
 </rich:treeNode>

 <rich:treeNode onselected="return false;" rendered="#{!item.enabled}">
 <h:outputText value="#{item.id} - #{item.name}" style="text-decoration: line-through;"/>
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor>
 </rich:tree>

Well, at least there is a workaround, but would it not make sense to have 'disabled' attribute on the treeNode? I already have a few "type"s for tree nodes with pretty complex things within the node, and have to copy/paste each one of them.

We'll consider that while planning new features for sure.
