[jboss-user] [JBoss Seam] - JBoss Seam + Facelets + Richfaces Tree error

I'm getting the following error once I tried to use the Richfaces Tree component: java.lang.ClassCastException: com.sun.facelets.StateWriter | at com.sun.faces.renderkit.html_basic.HtmlResponseWriter.endElement(HtmlResponseWriter.java:300) | at org.richfaces.renderkit.html.TreeRenderer.doEncodeEnd(TreeRenderer.java:248) | at org.richfaces.renderkit.html.TreeRenderer.doEncodeEnd(TreeRenderer.java:256) | at org.ajax4jsf.framework.renderer.RendererBase.encodeEnd(RendererBase.java:114) | at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:827) | at javax.faces.component.UIComponent.encodeAll(UIComponent.java:896) | at javax.faces.render.Renderer.encodeChildren(Renderer.java:137) | at javax.faces.component.UIComponentBase.encodeChildren(UIComponentBase.java:803) | at javax.faces.component.UIComponent.encodeAll(UIComponent.java:886) | at javax.faces.component.UIComponent.encodeAll(UIComponent.java:892) | at com.sun.facelets.FaceletViewHandler.renderView(FaceletViewHandler.java:571) | at org.ajax4jsf.framework.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:108) | at org.ajax4jsf.framework.ajax.AjaxViewHandler.renderView(AjaxViewHandler.java:229) | at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:106) | at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:248) | at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:144) | at javax.faces.webapp.FacesServlet.service(FacesServlet.java:245) My environment is Java 5, Tomcat 5.5.20, JSF 1.2_03, Facelets 1.1.11, JBoss Seam 1.2.0_patch1, JBoss Richfaces 3.0.0, Ajax4jsf 1.1.0 I tried to use the Richfaces dataList and it works, so I guess my configuration for Richfaces is correct. May I know if anyone has successfully used the Tree and TreeNode of the latest Richfaces under JBoss Seam? Thanks for your help.
