When processing event registrations through the Raiser's Edge/Luminate Online plug-in, users receive Error: Object cannot be cast from DBNull to other types.
If you used Event Mirror feature in Luminate Online to create the event in your Event Calendar and then copied a different registration form to make the new registration form, it causes a problem in the cross references for the event itself. The cross references for campaign, fund, and appeal will be correct, but the event cross reference will not.
To resolve, go to Luminate Online and remove the cross reference for the event. This will allow the transactions to process through the plug-in.
