Just try to output your map in multiple movies ("OUTPUT_MOVIE=MULTIPLE").
I expect this will not return fatal error but one swf for each layer in
your mapfile. Hope this works.
I don't even know why single output crashes. Is it due to ming library
or mapserver ?
If you are able with this method to generate movies, you'll just have to
redefined your Flash app to load each movie individualy.
I didn't work on this a lot but I think this might be a good way to
built a flash interface. I mean, layers may be hidden or shown
individualy easily and other great stuffs could be imagined.
It would also be great to have examples or experience returns from
people who succesfully explored this mapserver output possibility.
Regards.
