Hi all,
I have two classes:
Parent(1) and (*)Child.
I've spotted a weird situation. When I fetch a Parent object (with a
Child collection) using UniqueResult<Parent> and after that Update a
Parent (I didn't made any modifications on Parent nor any Child
objects) nhibernate inserts a new copy of each Child object into a
db.
Example:
We've got a one Parent entity P1 and four Child entities: C1, C2, C3,
C4 in the db. After a mentioned process (fetch + update) we'll got one
Parent P1 and eight Child entities - four original and four copies.
Could anyone explain me what happens?
More Info:
NH: 2.0.1.4
Parent.xml:
<hibernate-mapping namespace="namespace" assembly="assembly"
xmlns="urn:nhibernate-mapping-2.2">
<class name="namespace.Parent" table="parent" schema="schema">
<id name="ID" type="Int64">
<column name="id" not-null="true" />
<generator class="sequence">
<param name="sequence">sequence_name</param>
</generator>
</id>
...
<bag name="Children" table="children" schema="schema" lazy="false"
inverse="true" cascade="all">
<key column="id_parent" />
<one-to-many class="Child" />
</bag>
...
</class>
</hibernate-mapping>
