bug #9398
Updated by Andreas Müller over 3 years ago
Either this is a problem on the order of operations during save. Or it is a general issue with merge where it could be a problem that the name is loaded with taxonBase initialized. Or any other problem. How to reproduce: * Open any taxon with a synonym in name editor * use the synonym name as NameUsedInSource of a fact of this taxon * save * delete the synonym * save the taxon again => exception After reopening the name editor without saving the synonym is still gone (and also in the DB there is a delete event in TaxonBase for the synonym so it looks like the failing merge operation somehow runs ofter the delete operation. ~~~ last remote method : http://test.e-taxonomy.eu:80/cdmserver/rem_conf_am/remoting/taxonnode.service last remote request client time : 2021-01-18T14:13:09.862 last
