The <rich:treeNodesAdaptor> provides the possibility to define data models and create representations for them.

Figure 6.72. Expanded tree with <rich:treeNodesAdaptor>

The <rich:treeNodesAdaptor> component has a "nodes" attribute that defines a collection of elements to iterate through.

Collections are allowed to include lists, arrays, maps, XML NodeList and NamedNodeMap either as a single object.

The "var" attribute is used to access to the current collection element.

The <rich:treeNodesAdaptor> component can be nested without any limitations. See the following example.

Example:

...

<rich:tree adviseNodeOpened="#{treeModelBean.adviseNodeOpened}" switchType="client">

    <rich:treeNodesAdaptor id="project" nodes="#{loaderBean.projects}" var="project">

        <rich:treeNode>

            <h:commandLink action="#{project.click}" value="Project: #{project.name}" />

        </rich:treeNode>

    <rich:treeNodesAdaptor id="srcDir" var="srcDir" nodes="#{project.srcDirs}">

        <rich:treeNode>

            <h:commandLink action="#{srcDir.click}" value="Source directory: #{srcDir.name}" />

        </rich:treeNode>

    <rich:treeNodesAdaptor id="pkg" var="pkg" nodes="#{srcDir.packages}">

        <rich:treeNode>

            <h:commandLink action="#{pkg.click}" value="Package: #{pkg.name}" />

        </rich:treeNode>

    <rich:treeNodesAdaptor id="class" var="class" nodes="#{pkg.classes}">

        <rich:treeNode>

            <h:commandLink action="#{class.click}" value="Class: #{class.name}" />

        </rich:treeNode>

    </rich:treeNodesAdaptor>    

    </rich:treeNodesAdaptor>

    </rich:treeNodesAdaptor>

    </rich:treeNodesAdaptor>

</rich:tree>
