Hi guys,
I'm trying to use virtual entity, and created retrieve and retrieve multiple event handler in the data provider, they can work.

However, when I created a 'onexternalcreated' step and plan to put it into create handler of data provider, it occured an error.


Error:

Exception details:
ErrorCode: 0x80044184
Message: Invalid plug-in registration stage. Steps can only be modified in stages BeforeMainOperationOutsideTransaction, BeforeMainOperationInsideTransaction, AfterMainOperationInsideTransaction and AfterMainOperationOutsideTransaction.
Anybody know how to resolve it?
