NPE for category option combos

  Thread Previous • Date Previous • • Thread Next 
Hi,

After upgrading to v 2.22 r 21368 I am getting a NullPointerException back
from DHIS 2 (pasted below) when attempting to create a Category Option
Combo via the API.

URL via POST:
http://localhost:8090/dhis/api/categoryOptionCombos

with json:
{"name":"MALE","categoryCombo":{"id":"bZ8GuALBl4r"}}

Has something changed with Category Option Combos in v 2.22 that I need to
accommodate? I do notice that we hadn't ever been setting the code field
for these and it has never been a problem. Is that now a requirement? The
schema doesn't appear to require it.

Let me know.

Thanks,

Lorill
