Robin Jansohn commented on MYFACES-4678:
----------------------------------------
One more comment: We use Deltaspike JSF module and type-safe view configs in
this project:
https://deltaspike.apache.org/documentation/jsf.html#Type-safeView-Configs
My feeling is that it is somehow related as the actions to produce the error
simply involves forth and back navigation between the pages.
