Hi Anthony,
Just setting these two annotations:
@Id
@GeneratedValue

results in a native id mapping in hbm.
Btw, it can be handy to use an edatatype for the id eattributes and then set the annotation on the
edatatype.

Martin,

I have db table already , so I cannot update schema in runtime.

I am using DB2 , I had set the primary key with Identity attribute.
Now it is OK.

1 questions need your help:

I create 1 Network object and 1 Label object,
then I add Label object into Network object,
then save().

stacktrace :
============================================================ ======

insert="true" update="true" unique="false" type="int">
<column not-null="false" unique="false"

</class>

How can I work around this?

Reagrds,
Anthony

My guess is that it expects that either network or label already exist and it tries to update them
instead of doing an insert. Can you debug into hibernate and check which one is the cause?

Martin,

In Hibernate ActionQueue's prepareActions() ,
the Label object is in collectionCreations ,but the
ExecutableAction's persister(is a OneToManyPersister)'s

sqlInsertRowString is "update ....."

and

sqlDeleteRowString also is "update..."

no "insert..." or "delete ..."

It seems some setting let hibernate think the Label should be exist in
table.

Anthony,
This can happen if the id of label has a non-null value (or a value which hibernate interprets as an
existing object). What is the id value of label?
