Re: Two arrays sharing the same adress space.

OK. the double initialization was the problem. the first init was giving me a pointer, and the second one was returning nothing because the file did not exist, and i guess the compiler was reusing it... the problem was fixed like this, sorry for the confusion guy's and thanks for the help.

as it turns out. with the bug fixed the mounts array is left null because the file does not exist yet. so further in the program is i try to add to the array, nothing happens. and if i try "mounts = [[NSMutableArray alloc] init];" only the two arrays get the same pointer. transportTypes =
