[ome-devel] dataset.getname() gives error? Matlab

[Sebastien Besson]

Hi Ian,

a solution to your problem is to reload the datasets using the ContainerService.

% Create dataset ids array
datasetIds = java.util.ArrayList();
datasetIds.add(java.lang.Long(dataset.getId().getValue()))

% Load datasets
proxy =  session.getContainerService();
datasets = proxy.loadContainerHierarchy('omero.model.Dataset', datasetIds,[]);

% Read dataset name
datasets.get(0).getName().getValue()

Cheers,
Sebastien

Hello

I wonder if anyone can help me with this?
Given a valid imageId I'm trying to get the name of the  parent dataset using Matlab.

this snippet

ids = java.util.ArrayList();
ids.add(imageId); %add the id of the image.

         param = omero.sys.ParametersI;
         param.addIds(ids);
         service = session.getQueryService();
         list = service.findAllByQuery(['select l from DatasetImageLink as l where l.child.id = ', num2str(ID)], []);
         dataset = list.get(0).getParent();

         datasetId = dataset.getId().getValue()

runs fine & gives me a datasetId that looks good (ie matches what I see with insight)

However this line

dataset.getName()


Gives me the following errors

Error using omero.model.DatasetI/getName
Java exception occurred:
omero.UnloadedEntityException: Object unloaded:omero.model.DatasetI at d0c94c0
at omero.model.DatasetI.errorIfUnloaded(DatasetI.java:22)
at omero.model.DatasetI.getName(DatasetI.java:668)
at omero.model.Dataset.getName(Dataset.java:218)

Any help welcome at this point. I assume "Object Unloaded" is a clue here?

Thanks

Ian
