> If we have a chain of operators where multiple of them have operator state, 
> detection of the {{context.isRestored()}} flag (of {{CheckpointedFunction}}) 
> does not work correctly. It's best exemplified using this minimal example 
> where both the source and the flatMap have state:
> {code}
> final StreamExecutionEnvironment env = 
> StreamExecutionEnvironment.getExecutionEnvironment();
> env
>   .addSource(new MaSource()).uid("source-1")
>   .flatMap(new MaFlatMap()).uid("flatMap-1");
> env.execute("testing");
> {code}
> If I do a savepoint with these UIDs, then change "source-1" to "source-2" and 
> restore from the savepoint {{context.isRestored()}} still reports {{true}} 
> for the source.
