History Change kepp value "0" but changes appeared in property tab of CIT



I encountered a starnge behaviour : i want to create a new report using "History Change" CIT and (for example) Node CIT ...

But when i select CIT (in modeling a new view) the count keep show always "0" ...

Of course, cerating this new view/report, relating node and history change CITs with a "history" relation, the count of results remain so and always at "0" !!

When i edit a node, its history tab show us many changes (attribute value changes) ...Is there a bug in the count operation ?


thanks in advance
