Hello all!

Windows 2000 SP4, Hibernate3, HibernateTools 3.1 Beta4, Oracle 9i, Java 1.4.2

Issue
Cannot generate code from custom daohome.vm
I have also tried without modifying.

Look at

http://forum.hibernate.org/viewtopic.ph ... ht=daohome (same issue?)
http://opensource2.atlassian.com/projec ... se/HBX-601 (ok, i was too quick with this, sorry)

Do we have a bug or i'm i missing something?

hmm...can you try and enable logging (put a log4j.properties in the classpath) and post it here ? (or even better, try and reduce the usage and revevng'ed database to the simplest thing possible)

I tried with one table. It worked. At this point i knew that we have one table that has problem. I saw comment with db-tool in two fields: Primary 1, Primary 2. I have to ask from db designer what's so special about this table. I'll get back on Monday..
