[richfaces-issues] [JBoss JIRA] Created: (RF-11138) tree does not invoke selectionChangeListener in popupPanel
tree does not invoke selectionChangeListener in popupPanel
----------------------------------------------------------
Key: RF-11138
URL: https://issues.jboss.org/browse/RF-11138
Project: RichFaces
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: component-tree
Affects Versions: 4.0.0.Final
Environment: WinXP; JBoss 6.0.0.Final; RichFaces 4.0.0
Reporter: Bastian Ulke
I am having a tree for a selection of a node. To monitor a selection, I initialized the
attribute "selectionType" to "ajax", added the attribute
"selectionChangeListener" and made it point to a method of a managed bean.
Everyhting is working extremely well, if I put the tree onto the form straight away:
Everytime, a node is selected, the method is invoked and I get all the information I need
to determine the selected node. The definition is as follows:
<rich:tree var="item"
id="tree2"
selection="#{treeController.selection}"
selectionType="ajax"
selectionChangeListener="#{treeController.selectionChanged}"
rendered="true">
Now, I want to have the same tree in a popup panel. All I do is wrapping a
<rich:popupPanel id="abc2"> around it (so no moving to another place -
both elements are directly located under the <h:form> node). Surprise: Nothing
happens when a node is selected in the popup panel, the method, indicated in
selectionChangeListener is never invoked. I remarked, that also the hidden input element
form:tree2__SELECTION_STATE never changes its value throughout selecting differnt nodes.
Intersting: Adding toggleType="ajax" and
toggleListener="#{orgTreeController.toggle}" to the same tree, works well in
both cases.
Workaround:
1. Switch selectionType to "client"
2. Add a jsFunction and extend the controller with a property to accept the selected
node's id
<a4j:jsFunction name="jsSetSelectedId">
<a4j:param name="name"
assignTo="#{treeController.selectedId}"/>
</a4j:jsFunction>
3. Add a panel to the node's content and call the jsFunction from above in the onclick
event
<rich:treeNode>
<a4j:outputPanel layout="block"
onclick="jsSetSelectedId('#{item.id}');return true;">
