JBoss-4.0.4.CR2 and Seam 1.0.1.GA I am trying to implement my first SelectOneMenu.
I'd appreciate any help in figuring out why I am getting this ClassCastException. This is happening in the framework soon after method is completed. I am using a ModelConverter which is registered in faces-config.xml. The exception happens immediately after the "allModelsM" method. xhtml snippet is: | <h:selectOneMenu id="modelSelect" value="#{fleetManagerAdmin.selectedModel}" | converter="ModelConverter"> | <f:selectItems value="#{allModelsSI}" /> | </h:selectOneMenu> | | relevant parts of Backing bean, a StatefulSessionBean are: | @Stateful | @Scope(ScopeType.SESSION) | @Name("fleetManagerAdmin") | | public class FleetManagerAdminBean implements FleetManagerAdmin | . | . | @In(required=false) | public Model selectedModel; | public Model getSelectedModel(){return selectedModel;} | public void setSelectedModel(Model item){this.selectedModel = item;} | | @Out(required=false) | private SelectItem[] allModelsSI; | public SelectItem[] getAllModelsSI(){return allModelsSI;} | public void setAllModelsSI(SelectItem[] allModelsSI){this.allModelsSI = allModelsSI;} | . | . | . | | @Factory("allModelsSI") | public void allModelsM() | { | log.debug(">>>allModelsM.."); | allModels =
