CiviCRM Community Forums (archive)

I've recently upgraded a Drupal 6 site to CiviCRM 4.4.0, and we're seeing an error when just some people try to register for an upcoming event (they've registered for other events before, using previous versions of CiviCRM, without issue). We are also seeing plenty of other people registering for the same event without any problems.

Here's the error message and backtrace:

#10 /home/sites/default/index.php(17): menu_execute_active_handler()
#11 {main}

Looking at one particular contact that is having this issue, I'm wondering whether it might be related to their relationships or email addresses (they have two 'employee of' relationships and two email addresses, and I wondering whether they are entering different data into the profile exposed on the event sign up form. What i don't understand is why CiviCRM is not able to cope with what they are submitting.

Any input welcome.

note that that job only clears contribution/event sessions that have not been touched in the last 30 minutes. This is due to the fact that there might be some secure data in the cache. Any active pages should be left untouched. That said, i dont think there are unit tests to ensure that this function works as designed, so might be good to add some there

This scheduled job was enabled, and there is a possibility of timezone confusion as my server is in a different timezone from my user.
I've updated to 4.4.1, and that might help improve things.
I'll try to register the user myself through the front end and see what happens.

I noted a couple of other event registration errors relating to relationships that had not occurred prior to 4.4.0:

The user attempting to register was presented with the following error message:

"‘Sorry but we are not able to provide this at the moment. Relationship already exists’."

And the backtrace:

#7 {main}
In the cases that I looked at, the user had two relationships with organisational contacts already, and editing these relationships to ensure that the relationship that the user was referring to when submitting the event registration profile was a 'current employer' seemed to resolve the issue. Again, what i don't understand is why CivicRM is throwing an error in this situation. When a relationship already exists, surely it should simply update the relationship as needed (for example making it a current relationship if it was previously recorded as not current), and get on and complete the event registration. This seemed to work fine prior to 4.4.0.
