[Federico E. Carpi]

Hi.   This is a part mapping file:    <class name="artesanos.modelo.Region" identity="idRegion" key-generator="MAX">    <map-to table="regionGeografica"/>      <field name="idRegion"      type="integer"      direct="true"      get-method="getIdRegion"      set-method="setIdRegion"      required="true">         <sql name="idRegion" type="integer"/>       </field>        <field name="nombre"      type="java.lang.String"      direct="true"      get-method="getNombre"      set-method="setNombre"      required="true">       <sql name="nombre" type="varchar"/>     </field>    <field name="descripcion"      type="java.lang.String"      direct="true"      get-method="getDescripcion"      set-method="setDescripcion"      required="false">       <sql name="descripcion" type="varchar"/>     </field>       <field name="provincias"      type="artesanos.modelo.Provincia"      required="false"      collection="vector">       <sql name="idProvincia" many-table="regionProvincia" many-key="idRegion" />     </field>  </class>   The problem is: When I try add a new province, with the method addNewProvince(Province p).   I have the next exception:   org.exolab.castor.jdo.ObjectNotPersistentException: The object of type java.util.Vector is not persistent -- it was not queried or created within this transaction  at org.exolab.castor.persist.TransactionContext.writeLock(TransactionContext.java:886)  at org.exolab.castor.persist.ClassMolder.preStore(ClassMolder.java:1368)  at org.exolab.castor.persist.LockEngine.preStore(LockEngine.java:697)  at org.exolab.castor.persist.TransactionContext.prepare(TransactionContext.java:1071)  at org.exolab.castor.jdo.engine.DatabaseImpl.commit(DatabaseImpl.java:469)  at artesanos.TestBD.<init> at artesanos.TestBD.main   Some body know what is the problem ??
