Hi again,
I just found out that when I do this change:

i.e. the terrain object is created after the image editing is finished,
everything else is the same, then the loading of the resulting BIN file
crashes at a different location. Actually, the Image data is read before
the Terrain data in this case (as it should be), but something else goes
wrong.
to my cluster program, then it works.
Hm, that sounds strange. AFAIK the order of ::create calls determines
the internal id the FieldContainer object gets.
Then if the FieldContainer objects are recreated in sequence of their
ids, it might happen that one is undefined in the first code piece.
Is that correct?
Loading a BIN file that was created from
the Terrain scene still does not work, but I currently don't need this.
Did you try an OSB file?
I will look into this. Perhaps I made a mistake in the Terrain::changed
method, which is the place to react to field
changes (after endEditCP) and it can get very complex with many fields
and field dependencies.
However, I still think there meight be some problem in the serialization
routines, or is it normal that it is sensitive to such small changes?
Regards,
Christoph
