Collection Loading
------------------

                 Key: HHH-2641
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2641
             Project: Hibernate3
          Issue Type: Bug
    Affects Versions: 3.0 final
         Environment: Hibernate3, Postgresql 8.1
            Reporter: Frederico
         Attachments: src.tar.gz

I'm not sure if this is a bug, but no one answered me in the hibernate forum, so....

I have a collection that it is not loaded, in log it seems to be ok, but when i access the
collection there is no element. 

   <class
        name="entidades.bdufop.Sistema"
        table="sistema"
        schema="public"
...

            column="codigo"
            type="java.lang.String"
    ...
             <generator class="assigned">
            </generator>

        </id>

        <property

            insert="true"
            column="disponivel"
            not-null="true"
        />
