Hi Markus, I think it has been fixed in more recent Trinidad releases (1.2.12) as I cannot find any code that could throw a NPE in the hashCode method (all nullable attributes have null checks). So maybe you could try upgrading to a newer build? I see that you're using JSF 1.1, so Trinidad 1.0.12 should include the same code as my 1.2.12 version for that part of the code.
