Kenneth Knowles commented on BEAM-10700:
----------------------------------------
Can you provide some details on what you tried that didn't work? We do have a
lot of usage of {{ValueProvider}} so I'm hoping we can fix the docs or help you
out getting it to work.
> "Retroactively logging runtime parameters" guide simply doesn't work.

> The Java version of the "[Pipeline option
> patterns|https://beam.apache.org/documentation/patterns/pipeline-options/]";
> article simply does not work.
> When creating a PipelineOptions inside of a DoFn, all get methods that return
> ValueProvider<T> will return null instead. The closest working example I
> could find was from Google's guide on [ValueProviders in Dataflow
> templates|#using-valueprovider-in-your-functions]. The pattern involves
> passing the ValueProvider into a DoFn class's constructor, storing it, then
> later accessing it at runtime.
