I was looking on others datamodels that I have and got I little more confusing. I found this method:


  | 	@DataModel
  | 	public List<Step> getStepList(){
  | 		return useCase.getSteps();
  | 	}
  | 

And the dataTable that reads the DataModel:


  | <h:dataTable value="#{stepList}" var="stepVar">
  | 	<h:column>
  | 		<f:facet name="header">Name</f:facet>
  | 	     #{stepVar.name}
  | 	</h:column>
  | 	<h:column>
  | 		<f:facet name="header">Edit</f:facet>
  | 		<h:commandLink value="Edit" action="updateStep" />
  | 	</h:column>
  | </h:dataTable>
  | 

I do not know how Seam knows if it is a DataModel or a List when stepList is accessed, but it works pretty fine, also injecting the selected entity through a @DataModelSelection annotation.
