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. Script engine error: TypeError: valueOf is not a function. Script source: null, line: 0, text: <compiled script>. See next exception for more information. Error evaluating Javascript expression. Script engine error: TypeError: valueOf is not a function. Script source: null, line: 0, text: <compiled script> This error is completely irrelevant to the actual cause of the problem.
