When you work with AS 2.0 and classes you have to be aware of the fact that Flash MX 2004 (Pro) uses some kind of caching. When a AS 2.0 class is compiled an ASO-File is generated which is located “SYSTEM_HD/Documents & Settins/USERNAME/Local Settings/Application Data/Macromedia/Flash MX 2004/en/Configuration/Classes/aso”. There can be problems if you are working on a network drive which is mentioned this Flash Technote.
I work a lot with classes and came to another problem. A bigger project won’t compile with no error message or warning. In the timeline I had only:
_root.app = new App();
In my App-class I import and use several classes. By commenting out step by step every class I got the class which caused the silent error.
The class which caused the problem was probably compiled wrong or incomplete so the whole application won’t compile with any error message.
I got it working by deleting my aso files (the one who caused the error should be enough).
Took me quite some time to figure this out so my hint: if your project won’t compile and you have no idea why first delete the aso files.
There is also a tool for deleting the aso files and for accessing common (nested) folders of flash or other flash-related functions called Flashtray Tools. To run the Flashtray software you need do install the Mircrosoft .NET 1.1 Framework.
