My property is just like a static list, but populated by another class - so,
I used a DB List property.
What I want to show on select is different from what I want the stored value
to be, this is actually the purpose of DB List properties' "id name" and
"value name", but my experience showed the contrary...

I've already seem these
and also found important information about this subject on this mailing (
http://lists.xwiki.org/pipermail/users/2008-February/010417.html). But
didn't solve my problem.

Again, I just want to do the same as property "List of users" does, which is
when selecting it is shown "first_name+last_name", and when querying the
result is "XWiki.alias". I want to do something similar, but with my own
class, not XWiki.XWikiUsers.
For example:
XWiki.dbClass [which has: property1 (string), property2 (string)].
XWiki.class1Class [which has: property3 (dbList)=> XWiki class name:
XWiki.dbClass, id field name: property1; value field name: property2)].
