[rich:tree] Row key not available

[ronanker]

Hi all,

We are using RF 3.3.0 with JSP.

We 've got a strange message when we hide a rich:tree.

Row key: treeNodeAdaptator:1 isn't available!

Here is the code :

<a4j:commandLink action="#{myBean.toggleTree}"
 reRender="treePanel">
 <h:graphicImage url="#{contexte.icones['Folder.gif']}" />
</a4j:commandLink>

....

<h:panelgroup id="treePanel" rendered="#{myBean.treeHidden}">
 <rich:tree switchType="client">
 <rich:recursiveTreeNodesAdaptor
 id="treeNodeAdaptator"
 roots="#{myBean.root}"
 var="node" nodes="#{node.nodes}">
 <rich:treeNode id="treeNodeSousTache">
 ....
 </rich:treeNode>
 </rich:recursiveTreeNodesAdaptor >
 </rich:tree>
</h:panelgroup>

The message only appears with the following use case:

- click to show the tree.
- Uncollapse one node of the tree.
- click to hide the tree.
=> the message appears: The given id seems to be the uncollapsed node's one.

Any clue of what is wrong ?

Thanks for any reply.

what is the scope of myBean?

b.t.w. it isn't ok to reRender conditionaly rendered elements. It isn't a source of problem just for future.

Once again thanks for your quick reply!

myBean is in the request scope with a4j:keepAlive.
(a4j:keepAlive tag is outside of the rerendered panel)

About "conditionaly rendered elements", you're right and my sample code is wrong: The actual 'reRender' clause is rerendering another panelgroup embedding the 'treePanel'.

sorry.. checked under richfaces-demo environment and seems works ok.. do you able to send me war file?

Not easy to extract our code to a war.

Can you at least explain us what the "Row key not available" message mean ?

Hello,

This message is generated when expansion fails due to row data for the particular node is unavailable. As a workaround you can make toggling command link ajaxSingle="true".
