@alex: It happens in eclipse within a trivial Test-Application
@andrus:
Specially strange is that I have 2 developement-Computers
1: at the company
2: at homeoffice
both should be equal installed,
both are running with linux
at the company with SuSE 8.2
at homeoffice with Mandrake 10.1
the rest should be the same.
but at the company it's OK
at homeoffice the NullPointer ...
I suggest it is a configuration problem,
but I have no Idea where to start searching
It's a new project, with an intial database (postgres)
No special classes in use.
I will have a try with cayenne 1.2
