By reading the forum, it seems like lots of CF developers having difficulty to
consume web service either with input arguments with complex data or receiving
complex data type which returns from the web service. Can I suggest that
Macromedia that provide some sample codes to show all CF developers how to pass
the complex data type to web services or parse the return variables with
complex data type?

It is really annoying to see lots of CF developers banging their heads to
solve the same problem. Either the CF is not ready for web service or
something wrong with the CF web service interface... This is just my personal
opinion...
