Odd error, looking for some advice.

[Roger Schlachter]

We are getting the error below in our logs and having a hard time
diagnosing the problem. We've seen it happen on caseNote/edit and
caseNote/update, but it doesn't happen every time so my first thought
jumped to a data issue, but the data appears to be fine. Has anyone
else seen anything like this and have any advice?

Line 66 in the CaseNote object is :
if (owned()){

And owned() is defined as:
boolean owned() {
return ClinicUser.currentUser.id == client.clinicUser.id
}
