1. Create a new Subaward (or an Award, Proposal, etc.) or edit an existing Subaward (or an Award, Proposal, etc.), completing all required fields. You can try this on any KFS document too, I tried Budget Adjustment.
2. On the Subaward Actions tab, populate a new Ad Hoc Recipients subpanel row
3. Change the Namespace Code autopopulated by the system to something different
4. Click Add
The system displays a valid error message.
5. Click Save
A stack trace is thrown. While the system correctly identifies the wrong namespace code and errors while trying to add it, it tries to save this wrong data and throws the stacktrace at line 1196 in KualiDocumentActionBase because it was not able to find a group with the given criteria.
