[ome-devel] Accessing OMERO.insight attachements via the API.

[Bernhard Holländer]

Hi Jerome!

Have you tried just creating the link and saving that (python example):

link = ImageAnnotationLinkI()
link.parent = ImageI(image_id, False)
link.child = FileAnnotationI(annotation_id, False)
update_service.saveObject(link)

You would need to reload the image to get the updated annotation list.

Also it's sometimes useful to look at the Blitz0.log file in the
var/log folder of the server installation. The error messages are more
verbose there and might give a hint what's going wrong in your
example. It might not be correct to create the link via linkAnnotation
and save the link. I would guess you rather have to save the modified
image...

Hope that helps! Bernhard
