Bug 140974 bad assert in ScalarParameterFragment
The following assert appears around line 98 in org.eclipse.birt.report.viewer.aggregation.parameter.ScalarParameterFragment assert paramDefaultValueObj instanceof String; If the report does not have a default value for the parameter in the report, then this assert fails even though the code that follows it explicitly handles a null value. Since null is a valid value, the assert should be assert (paramDefaultValueObj == null) || (paramDefaultValueObj instanceof String);
