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.
model/org.eclipse.birt.report.model/src/org/eclipse/birt/report/model/command/LibraryCommand.java
for ( int i = 0; i < derived.size( ); i++ )
					{
						DesignElement child = (DesignElement) derived.get( i );
						if ( child.getRoot( ) == getModule( ) )
						{
							ExtendsCommand command = new ExtendsCommand(
									getModule( ), child );
							command.localizeElement( );
						}
					}
				}
			}
			LibraryRecord record = new LibraryRecord( module, library, false );
			getActivityStack( ).execute( record );
			
			String libraryFileName = library.getFileName( );
			assert libraryFileName != null;
			removeIncludeLibrary( libraryFileName, library.getNamespace( ) );
		}
		catch ( SemanticException ex )
		{
			stack.rollback( );
			throw ex;
		}
		getActivityStack( ).commit( );
