When you make a change to a relation, Cayenne validates the records at both ends of the relation in total. So for example, creating a new Painting and relating it to an Artist will cause the Artist validation to fire, even though no database columns in Artist were modified.
Yeah, this is annoying. I know what you mean.
The validation seems to fire across one relation, but not two, even if there is a flattened relationship in between.
Are you saying a flattened relationship change does not cause a validation event?
This is causing problems for us. What is the possibility that this could be disabled: perhaps a flag per relation or per entity or even across the entire context or datamap.
I would also like to make validation configurable. I've been thinking for some time of implementing validation as a DataChannelFilter tied to a @Validate annotation. This will allow to configure validation strategy at the filter level and/or annotation parameters.
