@DiscriminatorColumn

[jbbarquero]

Is it possible to specify a @DiscriminatorColumn using Roo for an entity that is going to be the parent of an inheritance structure?

I see that the "_Roo_Entity" class has a "declare @type: OpcionMenuApl: @DiscriminatorColumn;" sentence, but I see no options in the entity command to set a value for it.

(I know that I can put the @DiscriminatorColumn in the java class, but I prefer to obtain all the infrastructure using script Roo commands)

Thanks.

Looking at the EntityMetadata code I can see the @DiscriminatorColumn is added if the "inheritanceType" attribute of the entity command is specified as SINGLE_TABLE. There is also a code comment:

// Theoretically not required based on @DiscriminatorColumn JavaDocs, but Hibernate appears to fail if it's missing

Thanks for the explanation.

By the way, I think it would be a good idea to add commands to Roo for generating annotations for entities and attributes (JPA annotations, for instance)

Kind regards.
