Subject: auto increment and 0 question
Hi,
Im currently working on a project using an existing database and am writing
a new Api
to access the database using OJB and have the following problem.
In my database there are rescords with the value 0 for colomns that
"auto-increment"
and ojb is "recognizing" the materialized objects of theose records as new
objects, eg
an record with id=0, name="bram" is materialized as Test(0, "bram) and when
i store it with OJB
it is assigned a new "incremented" id.
I have looked thru the OJB code and found that
BrokerHelper.getAutoIncrementValue(FieldDescriptor fd, Object obj, Object
cv)
does the testing of the object if it "needs" an new id.
What i want to ask is if i change line
297 if ((cv == null) || ((cv instanceof Number) && (((Number)
cv).intValue() == 0)))
to
297 if (cv == null)
am i missing something or is my assumption correct that only
Object members (no primitive types like int, char, long) like Integer, Long
that are null are assigned a new value.

table TEST (
ID NUMBER(10) not null primary key,
NAME NUMBER(10) not null
)
public class Test {
Integer id;
String name;
public Test() {}
public Integer getId() { return this.id;}
public void setName(String name) { this.name = name; }
public String getName() { return this.name ;}
}
<class-descriptor class="Test" table="test">
<field-descriptor id="1" name="id" column="ID" jdbc-type="INTEGER"
primarykey="true" autoincrement="true" />
<field-descriptor id="2" name="name" column="NAME"
jdbc-type="VARCHAR" nullable="false" lengthe="255"/>
</class-descriptor>
