Many-to-one doesn't get updated

Hibernate version: 1.2.0b2

Mapping documents:

Code:

  <class name="Account">
    <id name="ID">
      <generator class="sequence">
        <param name="sequence">account_id_sequence</param>
      </generator>
    </id>

    <property name="Name" />
    <property name="StrippedName" />
    <property name="Ticks" />
    <property name="Gender" />
    <property name="CreationDate" />
    <property name="Flags" />
    <many-to-one name="Alliance" />
    <property name="AppliedForAlliance" />

  </class>

Code:

  <class name="Alliance">
    <id name="ID">
      <generator class="sequence">
        <param name="sequence">alliance_id_sequence</param>
      </generator>
    </id>

    <property name="Name" />
    <many-to-one name="Leader" />
    <many-to-one name="Coleader" />
    <many-to-one name="DefaultRank" cascade="all" />

    <map name="MemberRanks" cascade="save-update">
      <key column="alliance_id" />
      <index-many-to-many class="Account" />
      <one-to-many class="Rank" />
    </map>

    <map name="Applications">
      <key column="alliance_id" />
      <index-many-to-many class="Account, STGQ" />
      <element type="String" />
    </map>

    <list name="Ranks" cascade="all">
      <key column="alliance_id" />
      <index />
      <one-to-many class="Rank" />
    </list>
  </class>

Code between sessionFactory.openSession() and session.close():

Code:

alliance.Leader.Alliance = null;
session.Update(Leader);
_MemberRanks.Remove(Leader);
session.Flush();

Here nothing happens.

Code:

_Applications.Remove(account);
account.Alliance = null;
session.Flush();

Here, "account" is a member of Apllications - and, surprisingly? it works. After issuing the Flush, the databse holds NULL for "alliance" in that specific row.
