    ClassCastException with ArrayList when implementing SelectOn

    forumer
    forumer Nov 13, 2006 10:16 PM

      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:

          Is that all the code in the bean? or is there some @DataModel stuff. It looks to me as though its chokiing on outjecting via @DataModel

            No I didn't have @DataModel before as I thought SelectOneMenu is just plain JSF and not Seam specific. But upon your hint I did put in @DataModel/@DataModelSelection as shown below. But I get the same problem. Nothing I do, short of removing the relevant xhtml snippet, make the ClassCastException go away! I am doing something grossly wrong.

            Thanks for your help

             @DataModelSelection("allModelsSI")
 public Model selectedModel;
 public Model getSelectedModel(){return selectedModel;}
 public void setSelectedModel(Model item){this.selectedModel = item;}

 @DataModel("allModelsSI")
 private SelectItem[] allModelsSI;
 public SelectItem[] getAllModelsSI(){return allModelsSI;}
 public void setAllModelsSI(SelectItem[] allModelsSI){this.allModelsSI = allModelsSI;}

              I'd appreciate any help with this! I am stuck!

              Let me know if I can provide any further information.

                I think you're going to have to use your debugger on Component.outject to see whats going on.

                  Do you mean I need to debug Seam source code or is there another way you are referring to?

                  Even if I replace the problem xhtml with the following, I still get the same error! Do you think this could be problem because I am using 4.0.4.CR2 and Seam 1.0.1.GA?

                  Thanks for your help!
