Hi,

Does the metadata and schema below look okay?  I'm getting a
NullPointerException.

Hi Michelle,

The jdo and schema look ok to me. The orm has typos "IntField" should
be "intField" and "StringField" should be "stringField". Don't know
if the NPE is expected or a more graceful error message should be
"Unable to find field named "IntField"; perhaps you meant
"intField"?". ;-)

P.S. A good JDO? O, Gasp!

Hi Craig,

Thanks you for passing your eagle eye over these snippets.  I made the
corrections in the orm (three places for Object, SimpleClass, and
SimpleInterface), but I still get the same error.

Hi Michelle,

One more thing.

Hi Michelle,

issues of this nature (merging of the ORM file with the JDO file) should be
fixed in the most recent build - part of yesterdays changes

Hi Craig,

The spaces are an artifact.  They aren't in the .jdo file, nor in my
original email.

Hi Michelle,

This sounds like a good summer intern science project. Except we
don't have any summer interns. And science doesn't have the same
respect it used to.
