NPE when attempting to view entity with null valued, joined properties
----------------------------------------------------------------------

         Key: HBX-697
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-697
     Project: Hibernate Tools
        Type: Bug

  Components: eclipse  
    Versions: 3.2beta6    
 Environment: eclipse.buildId=M20060629-1905
java.version=1.5.0_07
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Command-line arguments:  -os linux -ws gtk -arch x86_64

    Reporter: Jacob L E Blain Christen
    Priority: Minor


I am getting a null pointer exception when attempting to view an entity in the properties view (e.g. clicking on a "Hibernate Query Result" after running some HQL through the console).  This isn't a super major bug but it is annoying because I was using hibernate console to get quick feedback on tweaks I make to my mappings while developing and lost a few hours on the assumption that the error was just HB Tools's way of telling me they were bad =(

This is happening on an object that has some joins to aggregate some optional data.  A snippet of the mapping:
        <join optional="true" table="item_instruments">
            <key column="item" unique="true" />
            <many-to-one name="instrumentInfo" column="item" unique="true" insert="false" update="false" />
        </join>

        <join optional="true" table="item_stackables">
            <key column="item" unique="true"/>
            <property name="stackSize" column="stacksize" type="java.lang.Short" />
        </join>

If any of the properties on the mapped object defined with joins are null, the following NPE occurs and the properties window does nothing (silently ignoring the problem):

-----------------------------------------

if you could give me a (simple) mapping and (raw) dataset that gives the error then it would help. thanks.

[Hibernate-issues] [Hibernate-JIRA] Commented: (HBX-697) NPE when attempting to view entity with null valued, joined properties

Jacob L E Blain Christen commented on HBX-697:
----------------------------------------------

so, looking at the source from CVS, today 2006/07/06, it looks like HibernatePropertySourceProvider#getPropertySource() needs to check for null being passed in in its if-else block of code.  i can't test this theory right now but i will do so when i get home in a few hours.
