[Flow] Exception after validation error

[Steffen Wickham]

Hello Winfried,

sorry for my late reply but got a very busy weekend.
I'm not sure if the following statement is completly true, but I
remember that every time you create a new "@Flow\Entity" annotated
object, the identifier will change until you persist it.

Grretings,
Steffen
