I am using FDT for Flex development and when I compile, and it tries to access a flv file, I get the error “cannot access local file”. This is obviously a security sandbox thing.
Now I tried adding crossdomain.xml to the root and it still makes the same error. I know somehow I need to add to my project use-network=false, but i cant for the life of me work out where the flex compiler additional arguments area is. I know in eclipse how to do it, but with the slightly modified FDT, i havent got a clue
Googling ‘FDT Security’ throws up a similar discussion here… might be related to your problem?
