[jboss-user] [JBoss Seam] - ClassCastException with ArrayList when implementing SelectOn
forumer

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 = em.createNamedQuery("findAllModels").getResultList();
| SelectItem[] allModelsSI= new SelectItem[allModels.size()];
| int i=0;
| for(Model m: allModels)
| {
| log.debug("allModelsM() model="+m);
| allModelsSI[i++] = new SelectItem(m);
| }
| log.debug("<<<allModelsM()");
| }
| .
| .
| .
|
|
Beginning part of stack-trace (quite long) is:
