Relationship between two MBO's

Hi Experts,

     I am developing an application with the relationship between two MBO's.

I created two tables Customers and Orders, I gave a foreign key to Orders table.

Now i created two MBO's by drag and drop those two tables into my mobile application diagram.

and gave relationship between these two MBO's  and deployed in to server.

now i  created the Mobile WorkFlow Forms Editor, then the deployed MBO i.e., Customer MBO drag and drop in to my Mobile WorkFlow Forms Editor's Flow design screen, and add Menu item as Get Customers. By selecting the each customer record that customer details from details talbe and customer orders from orders table should display in the next screen.

i am unable to do that, please suggest me.

Thanks & Regards,

Sravanya.
