lazy loading doesn't work inside <component ...>
------------------------------------------------

         Key: HHH-1843
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH=
-1843
     Project: Hibernate3
        Type: Bug

 Environment: Postgresl, Hibernate3
    Reporter: J=C3=BCrgen Rose


1. setting property lazy=3D"true" on a component has no effect at all

2. any many-to-one property within that component with lazy=3D"no-proxy" is=
 fetched right away, which leads to n+1 Selects

Example:

class User {
    ...
}

class MetaData {
    Date creationTime;
    User creationUser;
    Date modificateionTime;
    User modificationUser;
    ...
}

class Foo {
    String attr1;
    String attr2;
    MetaData metaData;
    ...
}=20

<class name=3D"Foo" table=3D"foo">
    <property name=3D"attr1" column=3D"attr1" />
    <property name=3D"attr1" column=3D"attr1" />
  =20
    <component name=3D"metaData" class=3D"MetaData" lazy=3D"true">
        <many-to-one name=3D"creationUser" class=3D"User" column=3D"creatio=
n_user" not-found=3D"ignore" fetch=3D"select" lazy=3D"no-proxy"></many-to-o=
ne>
        <property name=3D"creationTime" type=3D"timestamp" column=3D"creati=
on_time" />
        <many-to-one name=3D"modificationUser" class=3D"User" column=3D"mod=
ification_user" not-found=3D"ignore" fetch=3D"select" lazy=3D"no-proxy"></m=
any-to-one>
        <property name=3D"modificationTime" type=3D"timestamp" column=3D"mo=
dification_time" />
    </component>
</class>=20

This makes it unusable for us, therefore it is even a major issue.
