I found my query, something like this: #set($hql = "select obj.name, prop.value from BaseObject obj, StringProperty prop where ( obj.className='FormSMQ.EAClass' or obj.className='FormSMQ.PiacJ2Class' ) and prop.id.id=obj.id and prop.name='TypeFiche_RO'")

...

Now I need the JSON format of my JSON data provider (resultPage parameter: full name of the page to use as a JSON data provider for the table)

You can use https://github.com/xwiki/xwiki-platform/blob/master/xwiki-platform-core/xwik... as an example of a custom results page.

Thanks, I will give a try. With ResultPage, I wonder if I could use select list of livetable. Thanks you VERY much to make my week-end busy ;-)
