wrm does not properly handle ModelReference actor
The ModelReference actor runs externally defined workflows. This currently breaks some functionality in the wrm:
- opening a workflow from previous runs does not work since the external workflows are not stored in provenance.
- if there's an error in the external workflow, the execution row is not highlighted red in the current window.
- sometimes a new, separate row appears referring to the external workflow. (this might not be a bug, depending on your point of view).
