[BUG] Nested artefacts are not returned
Ref thread in Steps!13, nested artefacts cannot be retrieved. @xuyangy knows the details, and it is probably easiest to reproduce using his branch. Alternatively this might reproduce it:
- Create two artefact models, where one model has a list of the other artefact type
- Create and store instances of nested artefacts in the DB
- Make a job for a MessageWatcher which is given the parent artefact
- In the process method of the messagewatcher, retrive the nested artefacts from the list in the parent artefact
This currently fails, but only Xuyang knows exactly how.
