Get Total Item/Row Count Caused by: com.mansystems.ATS.Runner.exceptions.RunnerException: javascript error: Cannot read property '3' of null JavaScript stack: TypeError: Cannot read property '3' of null The widget name that I include is gridBetrokkenAL, because the class of the datagrid is mx-grid mx-datagrid mx-name-gridBetrokkenAL.
