Trace in FlashBuilder 4.7 not working

fixed the issue. Will look into that further As others have pointed out, trace only works when in debug.
If you want information to get dumped out when running "release", you'll need to use the logging api that flex provides.

I think the issue was by ths following , Ensure that the app has the necessary security rights and permissions to access that folder/file. Also ensure the folder exists.
I believe in the interests of keeping an app running in times of trouble, if you misconfigure a trace listener like this the app will continue without error.

this will help I'm doing everything by the book (I think), I've reviewed this problem multiple times, but I can't seem to get it fixed. The creationCompleteHandler function is b , Add event as argument to your listener:

protected function readData(event:MouseEvent):void 
{
    Alert.show("check check");
}

it should still fix some issue Because it is for Air/mobile only. Use the SharedObject in case of web applications.

wish of those help After looking at the source code, it turns out that calledfuncs is the required api to be used.

class GenerateSequenceDiagram:
    def __init__(self, driver_module):
        self.driver_module = __import__(driver_module)

    def get_functions_called(self, driver_function):
        self.driver_function = getattr(self.driver_module, driver_function)
        self.driver_function()
        # print(dir(self.driver_function))
        # print(self.driver_function.__name__)
        tracer = Trace(countfuncs=1)
        tracer.run('{}()'.format(self.driver_function.__name__))
        results = tracer.results()
        called_functions = results.calledfuncs
        for filename, modulename, funcname in sorted(called_functions):
            print('filename: {}, modulename: {}, funcname: {}'.format(
                filename, modulename, funcname))
        results.write_results()
