Active Report Data Tab Control

[Sagar]

I am trying to create a report using data tab control that will show product line in tab label and corresponding product type in list present in tab card.

I have created an Active report with a data tab control and set the Tab Label data item to product Line(product line uses Query 1).In the tab card I am showing a List with single column product type(based on query 2).I added product line in Query 2 to create master detail relation ship between List Query 2 and Query 1.(Query 1 is master and Query 2 is Detail).I created a connection for the data tab control based on Product Line.

This works fine only if product line is dragged in list,and the list shows blank if only product type is show in list.I also tried adding Product Line to properties of List to include it in scope but it still shows blank. Request your help and suggestions ,do let me know if you have come across this behaviour?
