I had this error, and my search led me to a note saying that message comes back when PHP is throwing an error. A quick look at the end of my PHP log showed what variable I had a typo in, and it was a quick fix after that.
Currently on one particular machine, I am getting the "Channel disconnected before an acknowledgement was received" error in the first call that the Air app makes to a php function. I tried running the php files with some debug statements, and those work fine, so its not a problem of php connecting to the database. Also the functions that are called from the flex, are getting called (its getting logged right down to before the last return statement) but the control never returns back to flex.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
