As always with flex, the most simple problems are the hardest ones to solve.
For example to get
FileReference to download a file from the server.
now you would think that creating a URLRequest followed by a simple call to the
FileReference's download() function should do the trick.
But think again cause that results in no error and no download either.
The save dialog shows up and then … nothing … NICE
Now the solution is very simple:
just declare your FileReference instance as a class variable, outside of the function from where you use it.
And boom it magically works.
Another nice undocumented flex feature that can cost a bit of hair-loss and some
time spend in a mental hospital.
lucky are those who use FileReference as a class variable from the beginning.
