I've tried to connect a flash XMLSocket with the pd network objects, but although it connected I couldn't receive data in PD.. And i see people here having the same problem.

I found the solution in the flash server documentation found here:
http://www.nullmedium.de/dev/flashserver/

It seems that when you send data to PD in the form of a string, you have to end the string with ';'
for instance:

"I am sending this text;"
Furthermore symbols used in PD are not allowed.. like the '$'
when PD parses the data, it reads one word at the time,
therefore any comma's or other symbols have to be escaped.
"I am sending this text\, escaping the characters PD shouldn't parse\! ;"

I hope this helps people,
and i hope that something like this may be added to the PD documentation!!!

Kind regards an eager PD-fan
