Bug 147558 Passing date parameters to drill-through reports
Due to the date/time format, I can't pass a date parameter to a drill-through report. The date/time input requires that the user enters the date in a very specific format otherwise, the viewer does not recognize it as a valid date. Therefore, I set my text box to be have the date/time format 'dd-MMM-yyyy HH:mm' which is user-friendly. When I bind the param to the drill-through report, it passes 'Jan 1, 20006 22:33' or something in that order. Then the report that was being called returns that it is not a valid date. There is no function to format a date object to a specific format (or that I could find).

		{
			e.printStackTrace( );
		}
		
		ScalarParameterHandle parameter = (ScalarParameterHandle) findParameter( paramName );
		
		if ( defaultValueObj != null && parameter != null )
		{
			defalutValue = ParameterValidationUtil.getDisplayValue( null,
					parameter.getPattern( ), defaultValueObj, locale );
		}
		
		if ( defalutValue == null && parameter != null )
		{
			defalutValue = parameter.getDefaultValue( );
		}
		return defalutValue;
