My db:
---------------
Currency
-Name (PK)
-Value
-.....
---------------
---------------
OldCurrencies
-id (PK)
-name (FK)
-value
---------------

Code:
public class Currency
    {
        public virtual ISet<CurrencyHistorical> Historicals{ get; set; }

        public virtual string Name { get; set; }
        public virtual string Symbol { get; set; }
.................

Code:
public class CurrencyHistorical
    {
        public virtual int Id { get; set; }
        public virtual string Name { get; set; }
        public virtual string Value { get; set; }


And the mapping Files.
Code:
<class name="Currency" table="tblWaehrung">
    <id name ="Name" column="name">
      <generator class="identity" />
    </id>

    <property name="Value" column="wert" />
...........
    <set name="Historicals">
      <key  column="name" />
      <one-to-many   class="CurrencyHistorical" />
    </set>
  </class>


Code:
class name="CurrencyHistorical" table="tblWaehrungHistorisch">
    <id name="Id" column="id">
      <generator class="identity" />
    </id>
    <property name="Name" column="name" />
    <property name="Value" column="wert" />
    <property name="Date" column="kursDatum" />
  </class>


And now my problem. in my code i Load a currency with cur = session.Get<Currency>('EUR');.
works fine so far.
Then i want to access the ISet by cur.Hisorical.Count.
Now Count is always 0, but when i do the query directly on my db i get some rows.
why doesn't my ISet get filled?

Now i profiled it and can see, that the OldCurrency-Entity is created, just the ISet is noch populated.
also tried it with IList and <bag>, doesnt change anything..
