Hi Ian,
<div><br>
</div>
<div>a solution to your problem is to reload the datasets using the ContainerService.</div>
<div><br>
</div>
<div>% Create dataset ids array</div>
<div>datasetIds = java.util.ArrayList();</div>
<div>datasetIds.add(java.lang.Long(dataset.getId().getValue()))</div>
<div><br>
</div>
<div>% Load datasets</div>
<div>proxy = session.getContainerService();</div>
<div>datasets = proxy.loadContainerHierarchy('omero.model.Dataset', datasetIds,[]);</div>
<div><br>
</div>
<div>% Read dataset name</div>
<div>datasets.get(0).getName().getValue()</div>
<div><br>
</div>
<div>Cheers,</div>
<div>Sebastien</div>
