Using Rules to Update the Data of a Relations Endpoints (Referenced Entities)

Question

I have a Rule which triggers on a Relation update. It then checks for the Entity type of the first endpoint of the Relation. Then checks for a specific field. When I try to set an action to change this specific field, I get these errors related to the Revision ID which I can't seem to figure out.

Notice: Undefined property: stdClass::$revision_id in drupal_write_record() (line 7030 of ...\www\includes\common.inc).

Notice: Undefined property: RedhenContact::$revision_id in EntityAPIController->saveRevision() (line 525 of ...\www\sites\all\modules\entity\includes\entity.controller.inc).

Notice: Undefined index: revision_id in EntityAPIController->saveRevision() (line 528 of ...\www\sites\all\modules\entity\includes\entity.controller.inc).

Notice: Undefined index: revision_id in EntityAPIController->saveRevision() (line 533 of ...\www\sites\all\modules\entity\includes\entity.controller.inc).

DatabaseTransactionNoActiveException: in DatabaseConnection->rollback() (line 1024 of ...\www\includes\database\database.inc).

Simply put, I need a specific field on an Entity to update when a related Relation is updated. This seems simple, but for some reason I cant get it worked out...

Answer 1

Just in case someone happens upon this, I did find a patch that provided the solution for this error. Turns out the Redhen module had some revision conflict with the entity API, so this patch here fixed the error, and it should be included in further Redhen updates
