[forge-dev] Scaffolding @Embeddable

[Richard Kennard]

Thomas,

Sorry for not being clear!

So it sounds like most of these issues are not Metawidget-related per se (i.e. generation of the JSF pages and managed beans)? Let me know if you need any 
specific help with anything Metawidget related.

Regards,

Richard.
