Bug 147977 Chart editor does not use container's column bindings
1) create data source 2) create data set: select * from customers 3) create table 4) bind country, customer name to table 5) group by country 6) create a binding for total_by_country which aggregates # of customers in each country. put a data element in group footer and bind to total_by_country 7) in group header put chart 8) in data tab specify inherit from container Result: You see columns for report data set created in step 2. Expected Result: Just 3 columns for the 3 bindings created in 4 and 6.
