Hi,
FIRSTLY, DONT DISCOURAGE BY the code i put here - u propably don't have to analyze it as the problem should be a common bug , when using POSTGREsql 8.2x
I use newest Postgresql (downloaded today), newest production jdbc driver as well as one build from CVS, and Hibernate 3.2.3
I updated them because I hoped that the problem is resulting from too old libraries.
The mappings rather OK - i can't find any bugs. I just can't put an integer value to some object because the following happens:
PS> Hte important note is that Grupa object (which means Group in english) is inserted to database, but Student fails to insert...
