Workflow, how about trigger on addRelation/deleteRelation/updateRelation ?

[apcloic]

Hi,

On Occurrences module, I would like to update the number of participants field when a participant is added or deleted.
I know how to do this using a workflow and a custom script like this but afaik there is no way to execute it based on addRelation/deleteRelation action so the best alternative option is a cron task.

How about a new option like "when a relation is added/deleted" ?

Regards,
