p：treeNode的渲染属性不起作用

Question

I'm using PrimeFaces v5.3. when using the render attribute for p:treeNode as shown below,

 <p:treeNode type="data" icon="fa fa-cloud" rendered="#{node.state == 'live'}">
     <h:outputText value=" #{node.name}" title="#{node.state}" style="white-space: normal;float: left;"/>
</p:treeNode>

Property not found exception is thrown,

Caused by: javax.el.PropertyNotFoundException: Property 'state' not found on type java.lang.String

However if I remove the rendered attribute alone it works fine, it seems like my object is considered as java.lang.String by EL, any idea ???

Answer 1

There is no any node.state in TreeNode(see here https://www.primefaces.org/docs/api/6.0/org/primefaces/model/TreeNode.html )

Use something else like: node.selectable, node.type, node.contains("something")
