Even if i manualy edit the code for the default file, it doesnt take it into account into DFP insert or update pages.
It just doesnt insert the default file name to the database when the file browse form field doesnt have anything in it. So it simply doesn't work as intended.
At least not to my system and i don't have DFP1 installed (i uninstalled it first) neither ADT. I only got WebAssist Web Development Suite installed nothing else currently.
