Bug 205709 Translation table is missed when report design is flattened
It happens when a report design with a localization property file and some library (otherwise it's not flattened!) is executed. Such report document has no transaltion table and then can not be localized. The problem is in org.eclipse.birt.report.model.util.ReportDesignSerializer#visitReportDesign which does not copy the translation table from ReportDesignSerializer#sourceDesign to ReportDesignSerializer#targetDesign.
model/org.eclipse.birt.report.model/src/org/eclipse/birt/report/model/util/ReportDesignSerializer.java
ElementFactory factory = new ElementFactory( targetDesign );
		DesignElement newElement = factory.newElement(
				element.getDefn( ).getName( ), element.getName( ) )
				.getElement( );
		IElementDefn elementDefn = newElement.getDefn( );
		if ( elementDefn.isContainer( ) )
		{
			int slotCount = elementDefn.getSlotCount( );
			if ( slotCount > 0 )
				visitExternalSlots( element, newElement, slotCount );
			List properties = elementDefn.getContents( );
			if ( properties.size( ) > 0 )
				visitExternalContainerProperties( element, newElement,
						properties );
		}
		localizePropertyValues( element, newElement );
		cacheMapping( element, newElement );
		return newElement;
	}

	 * Visits the container properties of the given element.
