Bug 143105 Invalid "row" binding reference does not generate an error
Open the attached report. The data item in the second column is bound to an invalid expression row["junk"] (no binding by the name junk exists). No error is generated when this report is run. The 2nd column simply shows empty values. EXPECTED: erroneous "row" references must be reported as error.
