Sergiu, this is great input, could you point me to something, which explains
how to use the AJAX Suggest Input with XWiki?

Hi,
The property type you are looking for is Database List Class. It allows
you
to create a list containing items of your choice.
So, what you need to do, is:
- Make a class called MediaHasActor, with two DBList properties, one
called
Media, one called Person.
- The field called "Hibernate Query" should contain something like:
select
prop.value
from
BaseObject as obj,
StringProperty as prop
where
obj.className='XWiki.MediaClass' and (replace with '
XWiki.PersonClass' for the Person field
prop.id.id = obj.id and
prop.id.name='name' and
obj.name <> 'XWiki.MovieTemplate' (replace with '
XWiki.PersonTemplate' for the Person field
Now the relating object will display two list boxes, one with movies and
the
other with actors. Of course, when you'll have thousands of movies and
actors, a select won't be the best option, so you will need to use an
AJAX-powered Suggest input.

Hello,
I have the following question regarding relationing 2 classes in xwiki. I
made a class Person with 2 properties (firstName, lastName) and a class
Media with a prop. (title) and then I made an object "Richard Gere" of
class
person and 2 objects "Pretty Woman" and "Autumn at New York" of
class
Media.
Now I would like to link somehow the 3 objects, i.e to say that Richard
Gere played in "Pretty Woman" and also in the other movie (media). How
can I
do that? I don't seem to understand how to link the already created
objects
one with another. For instance, I cannot create another class with 2
properties, one of type Media and one of type Person, because these types
don't appear under "Type" on "Add Property" panel.
Please help me understand how can I do that in xwiki.
Ps. I heard something about attachments but I don't really understand
how...
Thank you.
