The reverse engineering file looks like that:

<column name="FK_TBENUSTAT_ISTATUS" jdbc-type='' property="benutzerStatus" type="najs.model.BenutzerStatus" />
<foreign-key constraint-name="PK_TBENUTZER_STATUS" foreign-table="TBENUTZER_STATUS">
<column-ref local-column="FK_TBENUSTAT_ISTATUS" foreign-column="ISTATUS" />
<many-to-one property="benutzerStatus"/>
</foreign-key>

Then the model class has a property:
private BenutzerStatus benutzerStatus;

The table TZUGANG has also a foreign key which points to the TBENUTZER table.It's defined like that in the TZUGANG table mapping (reveng file):

<column name="FK_TBENU_ILAUFNR" jdbc-type='' property="benutzer" type="najs.model.Benutzer" />
<foreign-key constraint-name="PK_TBENUTZER" foreign-table="TBENUTZER">
<column-ref local-column="FK_TBENU_ILAUFNR" foreign-column="ILAUFNUMMER"/>
<many-to-one property="benutzer"/>
</foreign-key>

The model class Zugang.java is created and has a property
private Benutzer benutzer;

if i take a look at the Benutzer class again, i can see the inverse mapping to the table TZUGANG and there are suddenly two more properties defined:

private Set tzugangsForFkTbenuIlaufnr = new HashSet(0);

private Set tzugangsForFkTbenuIlaufnr_1 = new HashSet(0);

This sould not be the case i think, only one property should be created.
