Can not change ID of participant

[nclaidiere]

Hi, we had to change the RFID chips of some monkeys and we can not update it on the server.

At first I thought this was coming from a server connexion problem since we had similar problems when updating participants before, but strangely I can change all the parameters (alternate ID, name, etc) but not the main identifier, which suggest that there is something preventing only this parameter from updating (and nothing wrong with the server connexion). The error message is also a new one (see below).

I tried inactivating the participant to change it but that didn't work either.

I created a new participant, attributed it to a experiment and could still change the identifier.

I restarted the server, just in case, but that didn't work either. I also tried when no monkeys were performing the experiment.

Hum... any idea?
