I actually found out that the problem is raised entirely by the lazy
loading.
I do have a complex datamodell with a lot of foreign keys, composed
primary keys and so on. if access now a property over many foreign
relationships lets say
string myName = Entity1.ForeignEntity2.CompositeId.ForeignENtity3.Name
The last Property cannot be acces due to the following Exception:
NHibernate.LazyInitializationException was not treated.
Message="Could not initialize proxy - no Session."
Source="NHibernate"
StackTrace:

Using the debugger I can see that the entities in between are loaded
correctly. just the property of the last entity throws the exception.
For now I switched off lazy loading. But it slows down the application
tremendously, so I would be really interested on how the solve the
problem stated in the first post, while using lazy loading.
To add an additional thought to the original problem: the reason why I
want to bypass the firstlevelcache is that I want to discard all non-
persistent entities (which I added before) and retrieve only the
persistent ones (use case: the user enters data and finally hits
cancel).
If there is another way to approach that problem I would rally
