| 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,
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.
