Subject "PK Generation Strategy: Database-Generated" doesn't work
Date Thu, 01 Mar 2007 09:53:25 GMT

I just started playing a bit with Cayenne to find out how things work. 
Therefore I created a database (HSQL) with a single table and in the 
CayenneModeler set "Primary Key Generation Strategy" to 
"Database-Generated" and the "Auto Increment" field to "ID (INTEGER)" 
which is the column defined as Primary Key at the attributes tab. 
However when I try to insert a row in my test program I get an exception 
because I don't have an AUTO_PK_SUPPORT table in my database. But as far 
as I understand I don't not need this table if primary keys are 
generated by the database itself. Is there something else I have to 
configure to not need to have that table (It works fine if I create that 
table via "Generate Database Schema" but I would prefer to have the 
database doing that primary key stuff. Or is there any reason that it is 
better to use AUTO_PK_SUPPORT)?

Thanx for help.
