Known Issues

Pool selection for training instance

Situation: Editing of both adaptive and linear training instance with assigned pool causes pool unassign on save.

Example:

1. Create new training instance, fill out necessary fields and assign pool.
2. Save instance.
3. Edit any title, start/end time, etc.
4. Save instance.
5. Assigned pool is now unassigned.

Solution: After editing and saving an existing training instance reassign desired pool and save again.

This issue will be resolved in next release.
