Hello
I have a rich:tree component used like so:
<rich:tree switchType="client" value="#{MyBacking.logTree}"
reRender="selectedLog" var="item" nodeFace="#{item.type}"
nodeSelectListener="#{MyBacking.processLogSelection}"
style="width: 50px;">
<rich:treeNode type="folder"
icon="/img/logListFolderIconClosed.png"
iconLeaf="/img/logListFolderIconOpen.png">
<h:outputText value="#{item.name}" />
</rich:treeNode>
<rich:treeNode type="log" iconLeaf="/img/logFileIcon.png"
icon="/img/logFileIcon.png">
<h:outputText value="#{item.name}" />
</rich:treeNode>
</rich:tree>
and my MyBacking processLogSelection() method is:
public void processLogSelection(NodeSelectedEvent event) {
logger.info("In processLogSelection");
HtmlTree tree = (HtmlTree) event.getComponent();
nodeTitle = (String) tree.getRowData();
selectedNodeChildren.clear();
TreeNode currentNode = tree.getModelTreeNode(tree.getRowKey());
if (currentNode.isLeaf()){
selectedNodeChildren.add((String)currentNode.getData());
} else {
Iterator<Map.Entry<Object, TreeNode>> it = currentNode.getChildren();
while (it != null && it.hasNext()) {
Map.Entry<Object, TreeNode> entry = it.next();
selectedNodeChildren.add(entry.getValue().getData().toString());
logger.info("selected node: " + entry.getValue().getData().toString());
}
}
}
But when the page renders the tree (fine) clicking on a node highlights the node but nothing is logged from either of the bean logger calls - the method is just not being called. Any help answering why this might be would be greatly appreciated. Mark
EDIT Added suggested tags/simplified bean method - still doesn't appear to get response from the bean as far as logs go:
<h:panelGrid columns="2" border="0" width="100%" rowClasses="tt">
<rich:panel styleClass="panelLogTree" header="Log Select">
<h:form>
<rich:tree switchType="client" value="#{MyBacking.logTree}"
var="item" nodeFace="#{item.type}" reRender="selectedLog"
nodeSelectListener="#{MyBacking.processLogSelection}"
ajaxSubmitSelection="true" style="width: 50px;">
<rich:treeNode type="folder"
icon="/img/logListFolderIconClosed.png"
iconLeaf="/img/logListFolderIconOpen.png">
<h:outputText value="#{item.name}" />
</rich:treeNode>
<rich:treeNode type="log" iconLeaf="/img/logFileIcon.png"
icon="/img/logFileIcon.png">
<h:outputText value="#{item.name}" />
</rich:treeNode>
</rich:tree>
</h:form>
</rich:panel>
<rich:panel styleClass="panelLogOutput" header="Log Content">
<h:outputText escape="false"
value="Log content: #{MyBacking.nodeTitle}" id="selectedLog" />
</rich:panel>
</h:panelGrid>
</rich:tab>
Note the end rich:tab as this tree is rendering in a tab, from an included jsp file. My backing bean method is also now:
public void processLogSelection(NodeSelectedEvent event) {
logger.info("In processLogSelection");
}
FURTHER EDIT
Interestingly, I thought I'd rip back to a basic working model. I took the code from the RichFaces Demo Page. I modified the faces-config.xml to include the SimpleTreeData bean. I had trouble getting the bean code which reads the data file in (simple-tree-data.properties) so I used a FileReader instead. This built ok, and I got a modified index.jsp jsf page to list the simple tree example as on the demo page, except clicking on a list item didn't report the selected nodeTitle to the specified place (same problem).
I can see this either as the same problem reported above or the fact that the loadTree method in the SimpleTreeData.java bean has been changed. In the change, I removed the following lines and changed extraneous code as appropriate:
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
InputStream dataStream = externalContext.getResourceAsStream(DATA_PATH);
As mentioned earlier, I used a FileReader but does anyone think this problem could be related to me removing these 3 lines? As also listed above, my processLogSelection method doesn't use getCurrentInstance but I'm not sure it needs to if ajaxSubmitSelection="true" is listed in the JSF.
Stumped.
