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
* @param elementTypeName
	 *            the element type name
	 * @param name
	 *            the optional element name
	 * 
	 * @return design element, <code>null</code> returned if the element
	 *         definition name is not a valid element type name.
