[Ecm] Re: Seam DataModel/DataModelList utilisation

Mon, 14 May 2007 05:35:48 -0700 

Ok,

I used DataModel and @Factory to create my object.
So the Outjected type was my TaskModel but not DataModel type...

Finally I used @In and @Out and @Factory...


Thanks,

Benjamin

Hi,

The classCastException is when Component do that

         if (dataModelField!=null)
         {
setFieldValue( bean, dataModelField, name, wrapper.getWrappedData(dataModelAnn, dataModel) ); //for PAGE scope datamodels (does not work for properties!) 
         }


call
public Object getWrappedData(DataModel out, javax.faces.model.DataModel wrapper) 
   {
      return wrapper.getWrappedData();
   }

Hi,
Can you post your error stack trace?
Thanks

Hi all,

I'm fighting with these annotation of Seam...
I'm trying have a TaskModelList  like that :

public interface TaskModelList extends List<TaskModel>, Serializable {

}

An implémentation very simple  like that :
public class TaskModelListImpl extends ArrayList<TaskModel> implements TaskModelList { 
  private static final long serialVersionUID = 44L;
  public TaskModelListImpl() {
  }

  public TaskModelListImpl(List<TaskModel> list) {
    super(list);
  }
}

An my action Bean :

  @DataModel("tasks")
  public TaskModelList tasks;

  @DataModelSelection("tasks")
  @Out(required = false)
  public TaskModel task;

I have always this error
ClassCastException an my TaskModelListImpl when Seam want to cast it to DataModel... 
I thought that the annotation was sufficient...
Where I'm wrong ?

Thanks for all explanation...

Benjamin JALON
