Steps to reproduce issue:
1. Log into i2b2 webclient with access to at least project.
2. Navigate to Previous Queries section (there should be at least one previously run query listed)
3. Right click the previously run query and click rename
4. Enter a different name for the query when prompted and hit OK.

Expected result: The new query name should be saved and displayed in the Previous Queries section upon submitting.

Observed result: Nothing happens. The old query name still shows up in the Previous Queries section. There is no error message thrown in UI or in server log. The new query name is not saved in the database and is basically lost. This feature worked fine in i2b2 v1.7.06 but not in v1.7.07.
