Nikita Timofeev commented on CAY-2728:
--------------------------------------
Yes, trying to use byte array as a final resort do more harm. Never seen the
real usage of it.
Don't remember why {{IdGenerationMarker}} is serializable. Run tests removing
it and none failed.
> Add ExtendedType to generate user-friendly exceptions for internally used
> values

> Project: Cayenne
> Issue Type: Improvement
> Components: Core Library
> Affects Versions: 4.2.B1
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Minor
> Fix For: 4.2.B2
>
>
> We have some internal values that could be used in a DB query and cause
> exceptions. In that case all the information user get is a confusing message
> like this: "{{Haven't found suitable ExtendedType for class
> 'org.apache.cayenne.access.flush.IdGenerationMarker'}}". See CAY-2726 for
> example.
> We should add some special {{ExtendedType}} to handle those types and
> generate user-friendly exceptions.
