I was reading the FAQ's and noticed a question referring to primitive
primary keys...
http://db.apache.org/ojb/docu/faq.html#primitiveNull
"Primitive values (int, long, ...) can't be null, so OJB interpret '0' as null
for primitive PK/FK fields in persistent objects. Thus primitive PK fields of
persistent objects should
never be represented by a '0' value in DB and never used as a sequence key
value.
This is only true for primitive PK/FK fields (e.g. Integer(0) is allowed).
All other fields have 'normal' behavior."
I was wondering when this was implemented.
I am using OJB 1.0. (only because I get IncompatibleClass exceptions
when I try to use 1.0.3), and I have an object with a primitive long PK.
It also has a String name property.
I implemented the "findByTemplate" method from the docs, but when I
populate only the name of the object and try to find a similiar object,
I get null.
I have verified that there is a row in the database with the same name
as what I'm passing in.
Here is a segment of some debugging...
DEBUG accesslayer.RsIterator -
RsIterator[org.apache.ojb.broker.accesslayer.RsQueryObject[query:
QueryByCriteria from class org.jlab.mis.apps.mics.valueobjects.Organization
where [id = 0, name = Jefferson Lab], class descriptor:
org.jlab.mis.apps.mics.valueobjects.Organization]] initialized
DEBUG accesslayer.RsIterator - hasNext() -> false
It looks to me that OJB is trying to find an object w/ id=0 and
name=Jefferson Lab.
Why would it be trying to use the id=0 (according to the docs, this
shouldn't happen, unless that feature wan't implemented until after 1.0.1).
