Trying to cast org.richfaces.component.html.HtmlTree
I am using Seam 2.0.1.GA, Jboss 4.2.2
This is not a seam problem per se, but I am hoping someone has run into this...
I am using a rich:tree backed by a seam component.
I have bound the component to the bean using the binding attribute. I want the tree state to be retained as the tree is expanded/collapsed by the user.
Everything worked as expected.
So, I wanted to also expand the tree when the component is first created. I expected to do this by casting it as HtmlTree or UITree and calling expandAll().
This results in a classCast exception.
If I print out the classname with getClass().getName()
I can see that it is really an org.richfaces.component.html.HtmlTree. But I cannot cast it as such.
I assume that my problem is really a classLoader problem...
My Tree Binding
<rich:tree switchType="ajax" binding="#{subnetTreeImpl.nodeTableTree}">
....
....
The setter
public void setNodeTableTree( UIComponent nodeTableTree ) {
if ( this.nodeTableTree == null ) {
System.out.println("nodetabletree " + nodeTableTree.getClass().getName());
if ( nodeTableTree instanceof org.richfaces.component.html.HtmlTree )
{
System.out.println("nodetabletree is instanceof HtmlTree");
this.expandAll( (org.richfaces.component.html.HtmlTree) nodeTableTree );
}
else
{
System.out.println("nodetabletree is not HtmlTree");
}
}
this.nodeTableTree = nodeTableTree;
}
My build file started out based on the seam-booking example, with the richfaces-api in the ear lib dir, and richfaces-impl and richfaces-ui in the war WEB-INF/lib.
In order to access HtmlTree (fix classNotFound), I copied richfaces-ui and impl to the ear ./lib. This worked but results in the class cast exception.
I tried also removing these from the war ./lib dir, but this causes other classNotFound error.
I think I am going about this the wrong way ( moving jars around ); Is there something obvious that I am missing?
Here is my application.xml
<application> <display-name>Centina SA Client</display-name> <module> <web> <web-uri>client.war</web-uri> <context-root>/client</context-root> </web> </module> <module> <ejb>client.jar</ejb> </module> <module> <ejb>jboss-seam.jar</ejb> </module> </application>
jboss-app.xml
<jboss-app> <loader-repository> seam.jboss.org:loader=client </loader-repository> </jboss-app>
