Re: Can't generate primary key values for given Identity

Hi Björn,

is this the whole stack trace? Your mapping seems ok. Did you include 
the mapping for the HL-sequence (see repository_internal.xml)?
http://db.apache.org/ojb/repository_internal.xml.txt
Does your test pass with the in-memory sequence-manager?

regards,
Armin
