.NET Subworkflow + CheckpointManager hangs

[codehunter13]

Hi,
I've got a workflow with a subworkflow. (created with BindAsExecutor).
This works.
When i add a CheckpointManager it hangs when starting to run the first executor from the subworkflow.
When i remove the subworkflow and just add the the first executor from the subworkflow directly to the main workflow, it also works.
So it seems checkpointmanager and subworkflows don't work together?

Regards,
Glenn

In the meantime, tried it again. Now i see an exception. couple of weeks agao did't saw this, it just hanged...
My code changed so do'n know if they are the same error or separate things
`System.ArgumentNullException : Value cannot be null. (Parameter 'Must attach to a join context before starting the run.')

Thanks @codehunter13 for raising this. @lokitoth I am also having the same issue. I tried with 06_SubWorkflows sample.

First I tested without Checkpoint Manager - await InProcessExecution.StreamAsync(workflow, initialInput, runId, context.RequestAborted); this worked,
However when I tried with await InProcessExecution.StreamAsync(workflow, initialInput, checkpointManager, runId, context.RequestAborted); It moved to Sub Workflow Executor but did not invoke the first Executor of that subworkflow
