Question about Metadata and ITD generation

Implementing an add-on created with addon create advanced, is it possible to annotate a JavaType using AddonOperations and in AddonMetadata annotate another JavaType?

I have troubles with this kind of operations when the implicated JavaTypes are MVC Controllers and its formBakingObject where the Type referenced by formBakingObject is an Entity with OneToMany relations. In some cases this behavior becomes in something like infinite loop in Metadata notifiacations.

I don't know if this behavior could be related with the issue in Roo's Jira: https://jira.springsource.org/browse/ROO-2467

Could somebody give me some guidance?

Thank you.
