I loaded the MVP Concept Dictionary, and when y try to search present this error: 'Error while attempting to find concepts - could not execute query'
The issue appears to be on the demo site as well. For reproduction: go with the latest verion of Firefox to http://demo.openmrs.org/openmrs/dictionary/index.htm and log in as admin (Admin123). Typing anything longer than 2 characters in the search box make the error appear (the concepts are not searchable in this situation). I ran also a standalone-server on windows7 and that one appears to have the same problem.
