Hi, If you only want to change the appearance, you should definitely take a look at Trinidad's skinning features<http://myfaces.apache.org/trinidad/devguide/skinning.html>. You can change the appearance of every Trinidad component this way, while keeping the functionality. Is that what you're looking for?
As for you other question: what type of parameters does SWF expect? POST or GET?
