[jboss-user] [JBoss Seam] - Re: PAGE scope DataModel's selection not correct

[Holy Joe]

I made a cheap hack in outjectDataModelList() in Component.java that made things work as I expected (for a page-scoped DataModel in a session-scoped bean).  I changed this:


  |     context.set( name, wrapper.wrap(dataModelAnn, list));
  | 

to this:


  |     if(existingDataModel != null) {
  |         ((javax.faces.model.DataModel) existingDataModel).setWrappedData(list);
  |      } else {
  | 	 context.set( name, wrapper.wrap(dataModelAnn, list));
  |      }
  | 

I don't understand the bigger picture well enough to know if that is going to hurt me in other ways, though.  Will reusing the wrapper cause problems with non-PAGE-scoped DataModels, or perhaps there are other uses of DataModels that will break?  Is it always safe to cast to javax.faces.model.DataModel?

Of course, any advice on how to implement my app without using a page-scoped datamodel in a session-scoped bean is welcome, too.

Thanks,

Joe
