[xwiki-users] livetable with multiple class?

Hello, Livetable is somehow magic but ... (there are always a 'but') is it possible to use multiple Class? I read XWiki.LiveTableResultsMacros "#macro(gridresultwithfilter_buildQuery $className ... #set($class = $xwiki.getDocument($className).getxWikiClass())" => livetable use getxWikiClass method (and not getxWikiClasses :-( ) Here my problem in my nice xwiki 6.4.0 application: I created some Class/Sheet/Template with 2 common properties/field: I mean on each document Class I created this common property (same name, same source): this one by example - Name:P1_DgMoa_req Type: Database List - XWiki Class Name: FormSMQ.ListeDGClass - Id Field: Name DGId - Value Field: Name DGLib On my WebHome I paste this livetable: #set ($columnsProperties = { 'TypeFiche_RO': {"type":"list","size":10}, 'P1_DgMoa_req': {"type":"list","size":10}, 'doc.name': {"type":"text","size":10,"link":"view"}, 'doc.date': {"type":"text","size":10}, 'doc.creator': {"type":"text","size":10,"link":"creator"}, '_actions': {"sortable":false,"filterable":false,"html":true,"actions":["edit"]} }) #set ($options = { 'className': 'MySpace.MyClass', 'translationPrefix' : 'FormSMQ.livetable.', 'tagCloud': true, 'rowCount': 15, 'maxPages': 10, 'selectedColumn': 'doc.name', 'defaultOrder': 'asc', 'extraParams': "&space=${doc.space}" }) With one class ( 'className': 'MySpace.MyClass',) my livetable work perfectly but display only documents 'linked' with this class (doc with 'MySpace.MyClass' object) If I use 'className': '' (empty), livetable show all document on the space but my select list are not filled. I tried 'TypeFiche_RO': {"type":"list","size":10,'class': 'MySpace.MyClass' } with empty 'classname', but if I select a value in my select list, only document 'linked' with this class are displayed. I tried topFilters options (HTML fragment that will be placed in a "top filter" area in the same fashion as the Tag Cloud filter) 'topFilters': '<input type="text" size="15" name="doc.name" value="">', but no document will displayed. I didn't managed either (I don't know how to choose the field who is filtered by the new input tag) I don't know if someone understand my problem ( livetable with multiple class source), but every magics tricks are welcome to help me.
