Description

Please introduce a common ORM layer/package. Something like "org.apache.click.extras.orm" .
Just too much of the various Click ORM code look the same, so it could be in this package.

If there would be a "generic"(common) ORM implementation:

• the Click Pages would be really ORM independent, allowing to simply switch the ORM just by changing the filter in web.xml.
• support for many more ORMs could come: lot of code wouldn't be duplicated. Click could be listed in more places.
• a tutorial about Click+ORM would be 95% usable for any ORM with such a functionality - no need for extra documentation.
