Hallo!

I am using Hibernator Plugin (0,96) with Eclipse 2.1.3 and get a LazyInitializationException when executing certain Queries in the 'Query View' of the plugin.
In the result window appears an empty view.
Other Queries work fine.

What is the reason for the problem and is there any known solution?

Thanks
Kuwe.

Example Query: from beans.Person

Mapping:
<hibernate-mapping>

    <class name="beans.Person" table="PERSON">

        <id name="id" type="string" unsaved-value="null" >
            <column name="PERSON_ID" sql-type="int UNSIGNED" not-null="true"/>
            <generator class="identity"/>
        </id>

        <property name="name" type="string" >
            <column name="NAME" sql-type="varchar(16)" not-null="true" unique="true"/>
        </property>

        <property name="passwort" type="string">
            <column name="PASSWORT" sql-type="varchar(255)" not-null="true"/>
        </property>

        <set name="personenrolle" inverse="true" lazy="true">
            <key column="NAME"/>
            <one-to-many class="beans.PersonenRolle"/>
        </set>

        <set name="charakter" inverse="true" lazy="true">
            <key column="CHARAKTER_ID"/>
            <one-to-many class="beans.Charakter"/>
        </set>

    </class>

</hibernate-mapping>
