Problem displaying rich:tree (did not find parent form)

meghiddo May 19, 2009 5:20 PM

Hey all, I have a very simple tree just to get things rolling. Here is the code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:a4j="http://richfaces.org/a4j"
 xmlns:rich="http://richfaces.org/rich">
<head>
<title>Project Explorer</title>
</head>
<f:view>
 <body>
 <rich:tree >
 <rich:treeNode >
 <h:outputText value="Project 1" />
 </rich:treeNode>
 <rich:treeNode >
 <h:outputText value="Device 1-1" />
 </rich:treeNode>
 <rich:treeNode >
 <h:outputText value="Channel 1-1-1" />
 </rich:treeNode>
 </rich:tree>
 </body>
</f:view>
</html>

When I try to run this on my local server I get the following:

org.richfaces.component.EnclosingFormRequiredException: class org.richfaces.component.html.HtmlTree (id="j_id3") did not find parent form.

Any ideas what Im doing wrong here?

tree could not be created declarativelly. check our samples and documentation and create proper dataModel for the tree.

B.t.w. such declarative definition request already in our jira so you could vote for ithttps://jira.jboss.org/jira/browse/RF-4905

does that mean I need to add h:form? Because I did do that/

Or are you saying I am unable to manually defibe values for the nodes? That I need to do so dynamically

tree requires dataModel. You can't define it just by page tags.
