Ice Exception

[icaoberg]

This method is failing. Nonetheless, the did is valid and I can see the dataset in omeroweb. If I run our homebrew method

Code: Select all

In [13]: pslid.utilities.hasDataset( session, did )
Out[13]: True


I get that the dataset exists. But I get this

Code: Select all

In [12]: gateway.getDataset( did, True )

NegativeSizeException is an internal Ice exception pointing to the fact that something's gone wrong in the binary protocol. Almost always, the cause of this is a discrepancy between interface definitions. This would happen, for example, if you use the client libraries from one OMERO version to talk to another version of the OMERO server.
