/** |
Also available in: Unified diff
To support GUIDs in MetacatHandler.handleDeleteAction(), I've added in a new method:
deleteFromMetacat() - deletes a document based on the docid
This factors the deletion code out of handleDeleteAction(). handleDeleteAction() now does a docid lookup based on GUID, and if it is not found, reverts to the deletion based on docid instead.
