Current item in a Table Record with paging

Current item in a Table Record with paging

  
In my webblock I have a Table Record (TR) with pagination (Richwidgets). This woks correctly. This TR is in a Tab control.
In another Tab control I hav a Web Block that uses the TR.List.Current.ENTITY.Id  as an input parameter. While debugging the eSpace I discovered that the current Id is always equal to the first Id in the list of the TR.

How do I get the current record of a TR that has pagination?

Thanks.
