RichFaces portlet and h:selectOneMenu
Hello,
I've been developing a set of portlets for the 2.6.4 Portal Server, and recently am trying to integrate RichFaces components. I have a portlet that renders properly when using static (defined in the xhtml file) menu items, but when I try to read from a managed bean I get the following error (stack trace snipped):
Cause: javax.portlet.PortletException: Error process faces request Message: Error process faces request StackTrace: javax.portlet.PortletException: Error process faces request at javax.portlet.faces.GenericFacesPortlet.doFacesDispatch(GenericFacesPortlet.java:303) at javax.portlet.faces.GenericFacesPortlet.doView(GenericFacesPortlet.java:263) at javax.portlet.GenericPortlet.doDispatch(GenericPortlet.java:133) at javax.portlet.faces.GenericFacesPortlet.doDispatch(GenericFacesPortlet.java:244) (snip) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Unknown Source) javax.portlet.faces.BridgeException: Error processing render lifecycle at org.jboss.portletbridge.ExceptionHandlerImpl.processRenderException(ExceptionHandlerImpl.java:59) at org.jboss.portletbridge.AjaxPortletBridge.doFacesRequest(AjaxPortletBridge.java:281) at javax.portlet.faces.GenericFacesPortlet.doFacesDispatch(GenericFacesPortlet.java:300) at javax.portlet.faces.GenericFacesPortlet.doView(GenericFacesPortlet.java:263) (snip) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Unknown Source) javax.faces.FacesException: java.lang.IllegalArgumentException: Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectOne(provider).

If I comment out the testBean.items line, the page renders.
The appropriate managed bean method is
public SelectItem[] getItems() {
SelectItem[] ret = new SelectItem[1];
ret[0] = new SelectItem(1,"label");
return ret;
}
I'd appreciate any help. The error messages are less than clear, and searching through the forums showed lots of guesswork. The component demo I downloaded doesn't seem to use a selectOneMenu, and I was trying to avoid incorporating Seam if I don't have to (trying to KISS but it's difficult).
The included libraries in the project include:
commons-beanutils-core.jar
commons-digester-1.8.jar
jsf-facelets.jar
commons-lang-2.3.jar
richfaces-impl-3.2.0.GA.jar
richfaces-ui-3.2.0.GA.jar
portletbridge-impl-1.0.0B2.jar
portletbridge-api-1.0.0B2.jar
commons-collections-3.2.jar
commons-beanutils-1.7.0.jar
jsf-facelets-1.1.14.jar
(and I just realized that I may have collisions with the last two)
I've tried to write the config files following the wiki's advice. I can include them later if needed. I'd appreciate some advice on the selectOne/selectMany components in the RichFaces context.
