I sat down to crack this thing, and have made a completely new implementation of facebooking for Corona. No need to own enterprise or anything, just copy this and use it instead of your old lua code.
I did not bother to change any of the code, so this is how we’re using it. You need to clean it up and make adjustments for yourself.
We’re giving NO SUPPORT for this piece of code! 
With this Facebook implementation, you’ll get the publish_actions permission from the user and will be able to post photos, scores, achievements etc. No more facebook sdk error #5.
So why does this work? By checking the access_token validity with facebooks open graph server, we’re able to know if the access token is ok to use or not. If it is ok, then we can skip the login phase completely. Second, if the token is _not_ valid, we can clean up our facebook variables, logout the user (logout is not a global function in terms of Corona Facebooking, but app-sandboxed), and pop up the auth dialog.
How to use?
FaceSingleSignon(your\_listener)
local obj = {
message = "Message",
source = { baseDir=system.TemporaryDirectory, filename="image.png", type="image" }
}
FacePublishPhoto(obj)
local facebook = require("facebook")
local appId = "YOUR APP ID"
local fbListener
local fbCommand
local fbData
local fbCallback
local fbId

if label then print( label ) end
level = level or 1
if type(t) ~= "table" then
t = json.decode(t)
end
if t then
for k,v in pairs( t ) do
local prefix = ""
for i=1,level do
prefix = prefix .. "\t"
end
print( prefix .. "[" .. tostring(k) .. "] = " .. tostring(v) )
if type( v ) == "table" then
print( prefix .. "{" )
printTable( v, nil, level + 1 )
print( prefix .. "}" )
end
end
