There are times when Rational Functional Tester maps objects incorrecly, e.g. mapping a combo box as a check box (this seems to happen fairly frequently to me). To fix this, open the Object Map window (displayed after double clicking the object map file displayed in Script Explorer), select the object you wish to change, and make its “Proxy Class Name”, “Role” and “Test Object Class” match the relevant info from the following table.
Note: doing this can severely screw up your object map. It works for me, but it may not work for you. On your head be it should you chose to go fidding with your object map
