there is a TreeNodeChecked clazz ([1]) for use case like this.
I used it this way:
JSP:
...
<t:tree2 id="tree" value="#{tree.tree}" clientSideToggle="true"
varNodeToggler="t" var="node">
<f:facet name="analysisFolder">
<h:panelGroup>
<h:selectBooleanCheckbox value="#{node.checked}" />
<t:graphicImage value="images/yellow-folder-closed.png" border="0"/>
<h:outputText value="#{node.description}" styleClass="nodeFolder"/>
</h:panelGroup>
</f:facet>
...
</t:tree2>
<h:commandLink value="GO" action="#{tree.processNodes}"/>
</h:form>
...
Backing Bean (constructor or init() in case of Shale's ViewControler)
(btw. AnalysisFolder is an business object of me...)
-------------------------
tree = new TreeNodeBase("root","Analyses",false);
for (Iterator iter = listOfAnalysisFolders.iterator(); iter.hasNext();) {
AnalysisFolder element = (AnalysisFolder) iter.next();
tree.getChildren().add(
new TreeNodeChecked("analysisFolder", element.getName(),
element.getId(), false, true));
selectedIds.add(new SelectItem(element.getId()));
}
-------------------------
action method:
-------------------------
public String processNodes(){
List childs = tree.getChildren();
for (Iterator iter = childs.iterator(); iter.hasNext();) {
TreeNodeChecked element = (TreeNodeChecked) iter.next();
if(element.isChecked()==true) {
//do...
}
}
...
}
-------------------------

Hello everybody,
Can someone give me some guidance or just point me to a tutorial or any
document, that explains how to create a checkboxTree? I have sucessfully
worked with a tree2, but I need to create a similar tree but with check
boxes on each leaf.
I would appreciate any help. Thanks a lot,
Johnny
