GroovyRowResult.getProperty always raise exception when field value is null I offer implementation of getProperty(String property): public Object getProperty(String property) { try { Object value = result.get(property); if (value==null && !result.containsKey(property)) { // with some databases/drivers, the columns names are stored uppercase. String propUpper = property.toUpperCase(); value = result.get(propUpper); if (value==null && !result.containsKey(propUpper)) throw new MissingPropertyException(property, GroovyRowResult.class); } return(value); } catch (Exception e) { throw new MissingPropertyException(property, GroovyRowResult.class, e); } }
