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.

					addLibraryStructure( libraryFileName, namespace );
				return;

		Library library = module.loadLibrary( libraryFileName, namespace );
		library.setReadOnly( );
		ActivityStack activityStack = getActivityStack( );
		activityStack.startTrans( );
		LibraryRecord record = null;
		if ( action == SIMPLE_ACTION )
			record = new LibraryRecord( module, library, true );
		if ( action == RELOAD_ACTION )
			record = new LibraryRecord( module, library, overriddenValues );
		getActivityStack( ).execute( record );
		
		if ( module.findIncludedLibrary( namespace ) == null )
			addLibraryStructure( libraryFileName, namespace );
		activityStack.commit( );
