I need to make a call to an external system (through SOAP) when a new object is saved/updated/deleted. If the external call fails then I would like the save to also fail. I have looked at the documentation and a MapperExtension cannot change the flush plan to cancel if the external call fails.
I have looked at session extensions and it looks like they would work, but it seems far removed from my object. I would have to check each object in the session to see if it is the correct type and then execute the external method and then remove the object from the session if it fails. Is this the recommended way of binding an external action when modifying an object? I suppose I could add a before_insert method to my object and have a session extension that just checks every object to see if it has before_insert and if it does then execute it (and any errors would remove the object from the session).
