Hello,
I am doing something wrong as Cayenne is trying to use auto_pk_suport table
although I specified PK Generation Strategy to Database generated on User
and Role db entities. There is a join db entity (UserRole) with default
strategy, but i guess this is supposed to be set to default as one can not
select both foreign keys (userId, roleId). I am using mysql.
This happens when first trying to insert a record:
[INFO] access.QueryLogger LOCK TABLES AUTO_PK_SUPPORT WRITE
[INFO] access.QueryLogger UNLOCK TABLES
