I have been using RemoteObjects for quite a while now with AMFPHP. Suddenly, I am getting the error:
Client.Error.DeliveryInDoubt Error Channel disconnected This error seems to crop up quite a bit but there has never been any definitive answer as to why or what the fix is. The particular RemoteObject call has been working fine and nothing has been changed in the way that it is called from Flex. Other RemoteObject calls still work as they did before. I found a blog post at http://www.sephiroth.it/weblog/archives/2007/10/amfphp_and_mbstring.php that possibly explained the error but nothing in that post helped. Using Charles and what I know about the way Flex sends HTTP data (http://tech.groups.yahoo.com/group/flexcoders/message/113914) I see Flex batch up a set of HTTP calls. First it sends an flex.messaging.messages.CommandMessage with a value of 5; Then it sends all the batched up flex.messaging.messages.RemotingMessage messages with values that are the names of the functions to call on the server. Now, when the error occurs, the value of the flex.messaging.messages.CommandMessage is 12. Looking at the AMFPHP code (Actually in amfphp/core/amf/app/Actions.php) there is no handling for a value of 12 so the message is not handled and the code tries to load "Amf3Broker.php" which does not exist anywhere. This is what generates the "Client.Error.DeliveryInDoubt Error". The strange thing is that I have seen this CommandMessage of 12 in Charles and the call has been successful. Anyway, does anyone know why this error message is generated and how to fix it?
