Trying to use the same placeholder twice in a report generates the following error in the report-building interface: "Error when executing the query: ERROR: Incorrect number of query parameters. Expected 2, got 1."

This is the sample, contrived query: SELECT c.fullname,c.shortname,c.idnumber FROM prefix_course c WHERE c.idnumber LIKE '%.:term' AND c.idnumber NOT LIKE '%.:term' ORDER BY c.shortname,c.fullname.
