Treeview problems with 2.5.6

kya · 27 Oct 2010, 08:52

Hi,
I am trying a simple Treeview example which works well with Spring 3.0.2, but as soon as I change my pom.xml to use Spring 2.5.6 (a project requirement) the tree is not generated, the HTML shows a blank screen and Appserver Logs (Glassfish) don't show any errors whatsoever. The only difference I see is in the source of the generated HTML's (see below) which seem to have generated extra parameters for the PrimeFaces.widget.TreeView JS object in the Spring 3.0.2 case. Any Ideas?

Here is the .xhtml:

Code: Select all

<html xmlns="http://www.w3c.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.prime.com.tr/ui">
<h:head>
<title>Tree</title>
 <h:outputStylesheet name="styles/tree.css"/>
</h:head>
<body>
<h:form>
<p:tree value="#{treeBean.root}" var="node" dynamic="true" cache="false"
        nodeSelectListener="#{treeBean.onNodeSelect}"
        nodeExpandListener="#{treeBean.onNodeExpand}"
        nodeCollapseListener="#{treeBean.onNodeCollapse}"
        selectionMode="single"
        selection="#{treeBean.selectedNodes}">
<p:treeNode>
<h:outputText value="#{node}"/>
</p:treeNode>
</p:tree>
</h:form>
</body>
</html>

here is the generate HTML for Spring 3.0.2:

never mind: I was using '<context:component-scan ...' in spring-config.xml to load my Tree bean, as soon as I switched to to '<bean id=...' everything worked.

I have to add though that according to spring 2.5.6 Docs, '<component-scan ...' is a valid way to load beans. So I am still perplexed as to why this failed. I like to use annotations to declare beans so it is sad that this failed. Is this a problem in Spring or in Primefaces? any ideas?

Have you defined SpringFacesELResolver?

I had this defined:

<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
