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.
