Duh! Finger trouble. There was a problem with my test plan - there was
a space after the Javascript function call, and so the expression was
evaluating to "false " rather than "false".
Try enabling Debug on the While Controller - select the controller and
use the Help menu item to enable debug. This will log the condition
value.
