Weird behavior - frequently hangs on a one-to-one mapping

I have the following mapping:

Code:

    <class name="Run">

        <id name="id" column="run_id">
            <generator class="seqhilo">
               <param name="sequence">run_id_seq</param>
               <param name="max_lo">10</param>
            </generator>
        </id>

        <version name="version" />
        
        <property name="runTypeId" column="run_type_id" />

    </class>

    <class name="MsRun" table="ms_run">
    
        <id name="id" column="run_id">
            <generator class="assigned">
            </generator>
        </id>

        <version name="version" />
        
        <one-to-one name="requestedRun" class="Run" constrained="true" />

    </class>

The run table above is polymorphically associated to a few tables and ms_run is one of them. But I only need an association property in MsRun and hence I used the one-to-one. I tried the foreign generator but got an error and so I switch to assigned.

Anyway, this mapping works fine a few times and then it hangs on an update (probably from an internal flush 'cause I am not updating / flushing / commiting) to the run table. Its strange that its doing an update 'cause I don't have any transient/dirty objects referenced from the persistent objects. This is a query-only session, so I have not started a transaction.

My instincts point to the mapping, but I have no clue how to fix it. My last option is to run it through the debugger but am concerned about all the code generation that may prevent/hinder it.

I am pretty much stuck, so any help would be greatly appreciated.

Sorry, it was 2 in the morning here and I wasn't thinking. But anyway, this morning eveything seems to be working fine. And I don't see any update statements at all. I shall repost it under a different topic if it reappears. Thanks.
