Hmm. Looks like mysql doesn't like the NODE-fields to be nullable.
The storage layer uses the foreign-key schemes for NODE fields.
In the old storage layer the foreign key scheme is default defined as "NOT NULL". So all foreign keys are 'not null'.
In the new storage layer (with the storagemanagerfactory) this will be defined separately, so that for each field the indices and null/notnull are defined separately.
