After updating to Omero 4.8.8 I found strange behavior with Matlab code that worked OK previously.
The test code below (almost ready for exec) is an attempt to create new Plate, which is Child of some Parent Screen, and then add File Annotation to this new plate (annotation file is the same Matlab "test.m" file).
The annotation is added, but newly created Plate is disconnected from its Parent Screen, and becomes standalone Plate as one can see in Insight.
Crucial are 4 last lines - if they aren't executed, the new Plate is created correctly, but annotation is certainly not added.
Best regards,
Y.

screenid = 52;
plateid = 603;
newplate = omero.model.PlateI();
newplate.setName(omero.rtypes.rstring('jfgnjklsdfbajfhujawehlasjjkdnasfkljasdnfasjk'));
newplate = updateService.saveAndReturnObject(newplate);

link.setChild(newplate);
link.setParent(omero.model.ScreenI(screenid,false));

L = file.length();
fid = fopen(full_file_name,'r');
byteArray = fread(fid,L,'uint8');
fclose(fid);
rawFileStore.write(byteArray, 0, L);
originalFile = rawFileStore.save();
% Important to close the service
rawFileStore.close();
%
% now we have an original File in DB and raw data uploaded.
% We now need to link the Original file to the image using the File annotation object. That's the way to do it.
fa = omero.model.FileAnnotationI;
fa.setFile(originalFile);
fa.setDescription(omero.rtypes.rstring(description)); % The description set above e.g. PointsModel
fa.setNs(omero.rtypes.rstring(namespace)) % The name space you have set to identify the file annotation.
% save the file annotation.
fa = updateService.saveAndReturnObject(fa);
%
link = omero.model.PlateAnnotationLinkI;
link.setChild(fa);
link.setParent(newplate);
% save the link back to the server.
updateService.saveAndReturnObject(link);
