t:dataList and Sets

[Richard Wallace]

Hey all,

I was just trying to get a Hibernate mapped collection, a Set, displayed 
on a page with a t:dataList component.  Much to my chagrin I started to 
get exceptions like "javax.servlet.ServletException: ServletException in 
'/admin/departmentType/list.jsp': javax/servlet/jsp/jstl/sql/Result" 
which I thought was really odd since I don't use any such beast in my 
app, it's all Hibernate based.

I thought that maybe something was wrong with my collection mapping so 
tried just doing a <h:outputText value="#{myPojo.myMappedCollection}" /> 
and it displayed the correct data.  So I did some digging in the 
tomahawk docs and it says for "supported types see JSF Spec 4.1.3."  Of 
course, that is a spec doesn't include sets, only Lists and ResultSets.  
So I can only guess myfaces tried to map the collection to a ResultSet 
and failed and so gave the not so informative message.

Looking on the list for dataTable and Hibernate messages to see how 
people had coped with this I found that the t:dataTable component "can 
create DataModels directly from Sets".  So, what I'm wondering is why 
doesn't the t:dataList support this?

That would make life so much simpler for me and probably others using 
Hibernate like this.  Thoughts?

Thanks,
Rich
