@OnSave and asynchronicity

[Salomon Brys]

Hi there,

How is @OnSave treated regarding asynchronicity ?

Precisely, considering that I have a validation method that validate my bean and throws an exception when the bean is invalid.

Now, when I save my bean using ofy().save().entity(myBean); will the exception be thrown as expected or do I have to call .now(); to make sure that I can catch the exception ?

Other way to ask the question : is @OnSave annotation is called during ofy().save().entity(...) or during .now() ?

Thank you,
Salomon BRYS

It looks to me as if your code is called within ofy().save().entity(myBean); rather than the future's .now() method.

That would be fairly simple to test though, just create an @OnSave that always throws an exception.

Yup this is how it works. On save is called before save, not after.
