Thanks Max, that solves it.
The datastore viewer in development console kind of misled me to think
the field is not persisted at all. I have noticed that after adding
records with the serialized field set, the serialized field column is
not shown in the datastore viewer. But, as soon as I add one record
with the serialized field == null, the column is shown in the
datastore viewer.
Could this be a bug or there is something more that I am missing?
