Describe challenges in working with the current Rave implementations:
- rave-jpa application context is responsible for more than JPA related configuration 2. rave-commons has transitive dependencies to other rave projects 3. template to page conversion happens in the repository 4. shindig currently requires being run with unauthenticated requests 5. widget repository needs getbycategory rather than using object reference 6. properties organization is difficult to maintain 7. more needs to be configurable through admin properties 8. navigation elements are not dynamically driven 9. css customization is not well understood 10. application contexts are confusing at best
