[flexcoders] convert result from webservice to use in bytearray en uncompress

[amigo_fd]

Hello,

I'm testing some compression systems to make my webservice results
smaller.

Now I have a webservice with the following action:

input = test
output = <base64Binary>K0ktLgEA</base64Binary>

How can I uncompress this result in Flex ?
This code gives the error: "Parameter bytes must be non-null."
