Here's my XHTML code :

Code: Select all

<p:tree value="#{sandboxManagedBean.dictionaryDataTreeRoot}"
								var="node" selectionMode="single" dragdrop="true"
								selection="#{sandboxManagedBean.treeSelectNode}">
								<p:ajax event="select"
									listener="#{sandboxManagedBean.saveSelectedNode}"
									update="hitTreeUpdateNode" />
								<p:ajax event="dragdrop" />
								<p:treeNode>
									<h:outputText value="#{node}" />
								</p:treeNode>
							</p:tree>

Any idea about this error ?
