ExtendedDataModel and @DataModelSelection

[rshan.bob.shanahan.alascorp.com]

I've written a class for supporting dao based pagination using the ExtendedDataModel following the approach outlined here:

datascroller and Seam example

It works just fine, however, I'd like to be able to associate my component with a @DataModelSelection variable. Since my component is already a '@DataModel' I can't annotate it as such and it seems the @DataModelSelection annotation only works in conjunction with @DataModel.

Anyone have an idea how to accomplish this?

I'd appreciate any clues anyone might have about this.

Thanks.

Overriding DataModels works.

@Name("org.jboss.seam.faces.dataModels")
@Install(precedence=DEPLOYMENT)
@Scope(STATELESS)
@BypassInterceptors
public class CustomDataModels extends DataModels {
     
     @Override
     public DataModel getDataModel(Object value) {
          if (value instanceof DataModel) {
               return (DataModel) value;
          } else {
               return super.getDataModel(value);
          }
     }
}

Odd that this is not supported out of the box.

Hi, I already override getDataModel in DataModels. But i have no clue where to put @DataModel and @DataModelSelection using the custom ExtendedDataModel approach. Do you have another conversation component to do that to put those?

@DataModel
private PaginateDataModel<Result> results;

@DataModelSelection
private Result selectedResult;

Because PaginateDataModel is already a conversation bean, where I have

@In EntityManager em;

Please give me some clues
