one-to-one: foreign key: save Problem
-------------------------------------

                 Key: HHH-4015
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4015
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.2.6
            Reporter: Sandeep Vaid
            Priority: Critical


 I have one-to-one relationship between  class A and class B
        
        <class name="A" table="TEMPA" >
	     <id name="aaId" type="string" column="AID" length="10"> 
	      <generator class="assigned"></generator>
	    </id>

	 <one-to-one name="b" class="B" constrained="true"  outer-join="false" cascade="save-update" />
       </class>
	   
	   
       <class name="B" table="TEMPB" lazy="true">
	 <id name="baId" type="string" column="BID" length="10"> 
	   <generator class="foreign">
	    <param name="property">a</param>
	    </generator>
	  </id>
	
	<one-to-one name="a" class="A" />
      </class>
      
    Problem 1: When i try to save A, it fires :
    	  insert into HBLEARN1.TEMPB (BID) values ('1')
    	  and throws error :
    	  The insert or update value of the FOREIGN KEY "TEMPB.CC1246876555824" is not equal to any value of the 
    	  parent key of the parent table.  SQLSTATE=23503
    	  
    	  Why it is first trying to save 'B' instead of 'A' first ?
    	  
   Problem 2: With this mapping, if i set <property name="hibernate.hbm2ddl.auto">create</property> in hibernate.cfg.xml,
        It generates TEMPA whose aaId is the foreign key referencing TEMPB. This is also incorrect..
