Yes, you have reason, perhaps is a bug in FB 4.5. The best way to resolve this problem is export your project from 4.0 and import the same project to 4.5. But if you create a new project on FB 4.5 you will have "Send failed .....Netconnection.Call.BadVersion" error when you work with ZendAmf.
I'm having this same problem, did you find a resolution?
Hello, yes I resolved this problem, but the mistake isn't in the versión of Flex or Zend.
I build another file gateway.php but I didn't paste and copy the lines, I rewrited all the lines of the old gateway.php.
I think that Zend found some char that it don't like in the gateway.php file that we don't see or class declared.
Sometimes the error is not in the file gateway.php, but the mistake is in some class declared in the gateway.php, but that reason, you should begin trying with one class, if all its ok, try with the second class etc.
I begin to write a Flex program that make the gateway.php and a basic class for every mysql table with its fields, in 4 weeks I will have complete this program. If you was interested, tell me and I would send you an email when I finish this program.
