Resolution: Duplicate
> [Duplicate] Removing any JPA entity in an action, which is in a parameter
> value, causes ObjectNotFoundException

> Key: ISIS-2979

> Good example to create an action, with List<Entity> parameter, and remove
> these entities from the database in the action body. After the execution,
> this causes ObjectNotFoundException, because FormExecutorDefault calculates
> resultResponse with using snapshotArgs of ActionModel, which tries to refresh
> parameter, but it is deleted. JPA does not distinct detached and removed
> entity - stated in JpaEntityFacet - and the context treats it as detached (I
> think it is a good solution in JDO, entities with deleted state are ignored,
> but JPA sends back a detached state, even if it is deleted). A comment
> "//XXX whether DETACHED or REMOVED is currently undecidable (JPA)"
> warns it well, but a better solution is necessary. An acceptable solution is
> to catch the exception in parameter value refresh operation in
> EntityUtil.refetch.
