MaObjectSerializer Error: "Incomplete graph, check serializer configuration"

[Chris Muller]

Hi Hari, what this means is that Ma object serializer serialized a
reference to an object without including that object in the serialized
package.

That "missing" variable has the clue you need.  Take a look at the
MaFixedObjectBuffer(s) in there, it has an "oid", or object-id, that
is the object that *refers* to another object (via one of its #oids)
which did not get included in the serialized graph.  You need to find
out why.

First check what class it is by looking up its classId -- often that
can be enough info to solve the issue.  In the debugger, you could
evaluate:

   classIdManager classForId: 1234  "where 1234 is the classId in the buffer"

Also take a look at the buffers #oids.  Find out which one is not
known to the serilaizer by:

   oidManager objectWithOid: 1234 ifAbsent: [ 'this object not in the
serializer' ]

Once you know what kind of object, we can then figure out why it
wasn't serialized.
