I am trying to create a custom object in AS3 to pass information to and from a server, which in this case will be Red5. In the below screenshots you will see that I am able to send a request for an object from as3, and receive it successfully from the java server. However, when I try to cast the received object to my defined objectType using 'as', it takes the value of null. It is my understanding that that when using "as" your checking to see if your variable is a member of the specified data type. If the variable is not, then null will be returned.

This screenshot illustrates that I am have successfully received my object 'o' from red5 and I am just about to cast it to the (supposedly) identical datatype testObject of LobbyData:

However, when testObject = o as LobbyData; runs, it returns null. :(

Below you will see my specifications both on the java server and the as3 client. I am confident that both objects are identical in every way, but for some reason flash does not think so. I have been pulling my hair out for a long time, does anyone have any thoughts?
