Steve, True, my question is not Cairngorm specific. I'm just scratching my head here trying to find the right incantation to debug a garden variety Flex app.
The following scenerio is for trivial Flex application: I entered the following URL: http://localhost:8080/flex/play/helloFlex/helloFlex.mxml?debug=true Up pops a dialog saying: Where is the Flash debugger host running? (*) Localhost ( ) Other Machine Enter IP address [ ] [OK] [Cancel] Huh? I click OK Then another dialog pops up saying: A connection to the Debugger could not be established by Macromedia Flash Player 7. Make sure you have selected Enable Remote Debugging on the Debugger Panel's pop-up menu. Again, huh? I've had no luck finding this debug panel in FlexBuilder. Sigh. -Douglass Turner
