Run attached report design. Its group key binding column, "groupkey", is defined to refer to a non-existing data set column: dataSetRow["bad"]. However the actual error seen when previewing the report in BIRT designer: Table (id = 6): + A BIRT exception occurred: Error evaluating Javascript expression.
