Why doesn the Flex Builder debugging tool stop at breakpoints in components?
The safest way to set breakpoints in component files is to use the Files list. Start the debugging session, navigate in your application to where you want to start debugging. Click the Files button on the Debug Toolbar (select Menu Debug > Files). Select the component you want, usually the MXML or ActionScript files. The list strips out underscores in filenames and can be very long, but this method always works. Flex Builder will open a temporary file and set the breakpoints. Now you can proceed.
