[jboss-user] [JBoss Seam] - Generic List with @DataModel

When using generic Lists, I get compiler warnings. If I want to have a generic return type, which of the following two options should be done? (Note the use of a cast in the second option.) Also, what's the disadvantage to not using @SuppressWarnings? It seems like it's optional... @DataModel | @SuppressWarnings("unchecked") | public List<Something> getSomethings() { | return myQuery.getResultList(); | } Without @SuppressWarnings, the above gives the warning: Type safety: The expression of type List needs unchecked conversion to conform to List<Something> @DataModel | @SuppressWarnings("unchecked") | public List<Something> getSomethings() { | return (List<Something>) myQuery.getResultList(); | } Without @SuppressWarnings, the above gives the warning: Type safety: The cast from List to List<Something> is actually checking against the erased type List Why is this error showing up in the second case. If I'm casting, shouldn't I be able to leave off @SuppressWarnings with no problem? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4002125#...
