Ludovic,
I'm trying the custom mapping and I would like to discuss some issues
I have figured out so far:
- it doesn't seem that custom mapping is exported to class definition
XML therefore cannot be imported e.g. from a backup
oops.. right.. I forgot this one.. It's easy to add.
- I guess custom mapping for StaticListClass and
DBListClass is not
supported now but due to IMO wrong conditional logic in
XWikiHibernateStore.isValidColumnType() (should return false when
validtypes is null) you can have a custom mapping for such classes as
long as the class is not marked as MultiSelect (when setting
MultiSelect I'm getting ClastCastException from Hibernate). I
understand that implementation of full list class functionality when a
List class set to RelationalStorage might be difficult, but it would
be nice to have support at least for single field MultiSelect!
right.. this needs to be fixed..
- Can I mix custom mapping with the default one within
one class?
yes.. fields that are not custom mapped are still read/written in the
generic tables..
Now if the field is custom mapped in the future the result will be non
predictable for the data stored in the generic tables..

Thank you.

Hi Jiri,
The custom mapping feature is working.. There is a need for some
documentation and I haven't added the fields in the class editor to edit
them through the web.
Currently custom mappings can be enabled programatically for example
using plugins..
The best way to actually test the feature is to look at the test.
Of course there are some limitations.. Currently enabling a custom
mapping after already having data in the db is not a very good idea
(there could be problems).
