My bean is in viewscope. The problem occurs while submitting the form: {code} javax.faces.FacesException: ModelType (class java.lang.Object) must be either an Array, or a Collection at org.richfaces.renderkit.SelectManyHelper.getConvertedValue(SelectManyHelper.java:332) at org.richfaces.renderkit.SelectManyRendererBase.getConvertedValue(SelectManyRendererBase.java:108) at javax.faces.component.UIInput.getConvertedValue(UIInput.java:1030) at javax.faces.component.UIInput.validate(UIInput.java:960) at javax.faces.component.UIInput.executeValidate(UIInput.java:1233) at javax.faces.component.UIInput.processValidators(UIInput.java:698) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIForm.processValidators(UIForm.java:253) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:1172) at com.sun.faces.lifecycle.ProcessValidationsPhase.execute(ProcessValidationsPhase.java:76) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:593) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:304) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at com.ocpsoft.pretty.PrettyFilter.doFilter(PrettyFilter.java:145) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:684) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:471) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:402) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:329) at com.ocpsoft.pretty.PrettyFilter.doFilter(PrettyFilter.java:137) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:240) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:164) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:462) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:164) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:100) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:563) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:403) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:301) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:162) at org.apache.tomcat.util.net.JIoEndpoint$SocketProcessor.run(JIoEndpoint.java:309) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) {code} Sample code: {code} ... <composite:attribute name="beanAndValue" /> ... <rich:pickList value="#{cc.attrs.beanAndValue}" ... {code} I tried adding a type java.util.Collection, or java.util.List, but this had no effect. Note that it works when the picklist is outside of the composite component. It also works with an h:selectOneMenu works with similar code: I have NO trouble passing a list to the value of h:selectOneMenu ! {code} ... <composite:attribute name="beanAndValue" /> ... <h:selectOneMenu value="#{cc.attrs.beanAndValue}" ... {code} As this works outside the composite component and with similar components (selectOneMenu), I assume that the rich:pickList is not easy to integrate with composite components for some type issue, maybe the type gets lost and the picklist is very strict about it ?
