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

[Jerome Avondo]

Hi again,

Thanks again for the help, I've managed to push forward with all this... But... :)

I'm now trying to write some methods to copy annotations from one object to the other.
I have no problems with ratings and tags but I'm still finding fileannotations tricky.

Say I have an image, which already has a fileannotation associated with it. Now I want another Image to have the same fileannotation attached to it as well... I don't want to duplicate the file. Just want the second Image pointing to the same file.

so I tried,

using the loadAnnotations() from the IMetadataPrx object, to get all annotations for  my ImageID and of type ome.model.annotations.FileAnnotation. Which seems to work fine as I can get to the data that way.

Then I try to set the retrieved FileAnnotation objects to my second Image object, using the Image member function, linkAnnotation(), to create a ImageAnnotationLink which I then save the new link to the database via the gateway saveObject(). But this doesn't work. 
 
When I try and save the link, I get, message = "could not insert: [ome.model.annotations.ImageAnnotationLink]; nested exception is org.hibernate.exception.ConstraintViolationException:"

I also tried creating a new FileAnnotation object, and pointing it to the OriginalFile of the retrieved FileAnnotation. Still same error, when saving the link.

And I also tried retrieving the FileAnnotation or OriginalFile objects by their ids via queries, thinking I might not have the full objects loaded, but same issue...

Running out of ideas, any help welcome....

Thanks,

J.
