ok, I'll try that (recompile takes time) but an intermediate information 
is that the situation occurs only when the same datasource is used for 
reading and writing. I'm converting Polygons into LineStrings, so I'm 
reading from the database the polygons from one table and writing back 
lines into a different table. Now when I had two datasource objects to 
the same database the problem did not occur again.
