Bug 176436 Charts Imported from Libraries do not update when libraries change
During a live presentation of BIRT at EclipseCon, we came across a rather embarassing issue. When charts are included in a library, and imported into a report design from a library, any changes to the library instance of the chart do not reflect in the report itself.

if ( library.getHost( ) == module )
				break;
			library = (Library) library.getHost( );
		}
		assert library != null;
		String namespace = library.getNamespace( );
		IncludedLibrary includedItem = module.findIncludedLibrary( namespace );
		String path = includedItem.getFileName( );
		Map overriddenValues = null;
		ActivityStack activityStack = getActivityStack( );
		activityStack.startSilentTrans( true );
		try
		{
			
			
			
			overriddenValues = dealAllElementDecendents( library, RELOAD_ACTION );
			doDropLibrary( library );
			doAddLibrary( path, namespace, RELOAD_ACTION, overriddenValues );
		}
		catch ( SemanticException e )
		{
			activityStack.rollback( );
			throw e;
