Gail Badner commented on HHH-2075:
----------------------------------

I've reproduced this in master. It seems that properties within a <properties> tag are not processed correctly.

This test case has:
  <properties name="defaultPixelsTag">
    <property name="defaultPixels" type="java.lang.Boolean"/>
    <many-to-one
        name="image"
        class="Image"
        column="image"
        not-null="true"
        unique="false"
        cascade="lock,merge,persist,replicate,refresh,save-update"
        insert="true"
        update="true"        
     >
     </many-to-one>
   </properties>

    <property name="sizeC" type="java.lang.Integer" 
        not-null="true" unique="false" 
        update="true"
     />

Merge is not being cascaded to the many-to-one, and sizeC is erroneously nullified.

> Full test directory zip (org/hibernate/test/properties) attached. But to summarize, the following test will fail on flush after a simple merge. The exception thrown says that Pixels.sizeC is null -- though it's clearly set in the test case.
> <code>
>         Image i = new Image();
>     	
>     	Pixels p = new Pixels();
>         p.setSizeC(new Integer(2));
>         p.setImage(i); 			// This calls i.getPixels().add(p)
>         // i.setPixels(null);		// This makes it work.
>         
>         Session s = openSession();
>         Transaction t = s.beginTransaction();
>         // s.merge(i);				// This makes it work.
>         p = (Pixels) s.merge(p); 	// This fails with the exception below.
>         t.commit();
>         s.close();
> </code>
> The properties element in question is:
> <code>
>     <properties name="defaultPixelsTag">
>         <property name="defaultPixels" type="java.lang.Boolean"/>
>         <many-to-one name="image" class="Image" column="image"
>             not-null="true" unique="false"  insert="true" update="true"        
>             cascade="lock,merge,persist,replicate,refresh,save-update"
>          />
>      </properties>
> </code>
> The reverse side is:
> <code>
>     <set
>         name="pixels"
>         lazy="true"
>         inverse="true"
>         cascade="lock,merge,persist,replicate,refresh,save-update">      
>         <key column="image" not-null="false"/>
>         <one-to-many class="Pixels"/>
>     </set>
> </code>
