I tried adding a progress bar to a flex application, showing the progress of a function.  
(i’m new to flex, not so new to flash…)

then i found out that the progress bar’s source can be a display object only… ☹ like so:  
progressBar = new ProgressBar();  
progressBar.source = loader (or image…)

do anyone knows a way to use progress bars in order to show the progress of a function?  
thanks.
