CallingJdoPreclear tries to add the same instance to multiple 1-M relations
---------------------------------------------------------------------------

                 Key: JDO-414
                 URL: http://issues.apache.org/jira/browse/JDO-414
             Project: JDO
          Issue Type: Bug
          Components: tck20
    Affects Versions: JDO 2 final
            Reporter: Marc Prud'hommeaux
            Priority: Minor


The CallingJdoPreclear test tries to add the same instance to multiple 
one-to-many relations in different instances, which may result in validation 
errors at commit time. The code that does this is:

        primaryObj.addChild(secondaryObj);  // primaryObj contains one child;  
secondaryObj contains none. primaryObj is now dirty
        ... 
        ternaryObj.addChild(secondaryObj);

Errors can be worked around by removing secondaryObj from primaryObj.children 
before adding it to ternaryObj. E.g.:

        primaryObj.addChild(secondaryObj);  // primaryObj contains one child;  
secondaryObj contains none. primaryObj is now dirty
        primaryObj.children.remove(secondaryObj);

        ...
        ternaryObj.addChild(secondaryObj);

Alternately, the call to "primaryObj.addChild(secondaryObj);" can probably just 
be skipped ... it doesn't look like it would impact the test case.
