[#3068] - Ad-Hoc Report: Error with 2 Fields with same name from 2 different tables

We have two tables of the same datasource.
1st table "products" has the field called "name"
2nd table "stores" has the field called "name"
I select both fields to appear in the domain.

After creating a domain I want to create an ad-hoc report.
After I have chosen my domain an error occurs:

Can you help?
