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

[Will Moore]

Hi Ian,

 This query should load the Datasets
 
'select l from DatasetImageLink as l left outer join fetch l.parent as ds where l.child.id = '

Maybe even 

'select l from DatasetImageLink as l left outer join fetch l.parent where l.child.id = '


NB: I noticed you didn't use your param object below.

Try 

> list = service.findAllByQuery('select l from DatasetImageLink as l left outer join fetch l.parent where l.child.id =:ids ', param);



  Will.
