I read a bunch of threads on social.msdn regarding issues with Event Recievers on custom lists that fires twice, but I’m not sure this is the current problem I have. I have been using SP Manager and Event Handler Explorer to see if I could find any duplicate event handler registrations, but it’s empty. I’m almost out of any more hair on my head to pull out.
The site/list where the problem occur comes from a SP-Export/SP-Import, some functionality like workflows, webparts and the Event Recievers is deployed thru a feature. The thing is, if I disable the feature which contains the Event Recievers, it is only fired once. ‘
If I enable the feature again, it is fired twice. So it seems that this Event Recievers is stocked on the custom list, even though the feature is disabled. I have been trying to do some housecleaning on the feature_deactivating method, where I delete any Event Recievers on the custom list, but it doesn’t seem to do anything.
If I browse through the Event Handler Explorer, the only two EventHandlers I can find on the list is
Microsoft.SharePoint.Workflow.SPWorkflowAutostartEventReceiver, ItemAdded Microsoft.SharePoint.Workflow.SPWorkflowAutostartEventReceiver, ItemUpdated
And not the one I have been created.
What is going on?
