Work Description: TheNeuralBit commented on pull request #12067:
URL: https://github.com/apache/beam/pull/12067#issuecomment-649168647
I have a POC working that solves the problem by fixing all of the component
IDs in the external transforms in `to_runner_api()`. It feels pretty
error-prone, but it doesn't maintain any global state, and keeps all of the
special logic within ExternalTransform. I'll clean it up and push it here
tomorrow morning.

> The "unique ref" ids used in PipelineContext are generated on the fly, which
> can cause us to get a different id for the same component in different
> contexts.
> This becomes a problem when ExternalTransform is used, because it creates its
> own pipeline context for expansion. So its possible the component ids in the
> expansion request will actually refer to an entirely different component when
> the pipeline is finally assembled for execution.
