Revision 5186

Added by Jing Tao almost 15 years ago

Fix the bug of http://bugzilla.ecoinformatics.org/show_bug.cgi?id=4645. handleGetRevisionAndDocTypeAction will search both xml_documents and xml_revisions table.
It also changed some constrain in AccessionNumber when user update a document, of which all previous versions are in xml_revisions table.
