Custom Field that is a Foreign key to contact in Custom Group that extends Event is not updated on merge of contacts

Question

I have created a Custom Group for Events. This Group has one custom field Organizor which is a autocomplete with contacts. But on merging the contact the Organizor custom field is not updated accordingly.

Answer 1

This is something not handle in CiviCRM at the moment when two contacts are merged. I am not sure if any one has submitted fix for this issue. You can either fix this by adding code to update contact_id for all contact reference custom field in core or through hook_civicrm_merge hook via extension.
