Evaluate if entities should really be Comparable

[vitorsouza]

If I recall correctly, the CRUD mini-framework requires that for listing entity instances that are put in the trash can for deletion. Is this really necessary?

Suggestion: when creating the trash can, ask if selectedEntity instanceof Comparable. If true, use a SortedSet, otherwise use a regular Set.

Also, check the data table components used in the listing and in the trash. It might be interesting to use a data table that automatically sorts the entities...
