Hi Graham, Thanks for the reply. It helped solve some follow up issues after I overcame the below problem. The cause of this problem was the fact that the action script class representing the java object was never specifically referenced in the action script code because arrays were being passed back and then being set on the Model object (ie no casting was needed). Once the VO Action Script class was imported into the command class then everything started working as per normal. Now in hindsight this makes sense because if there is no direct reference to the VO then flash never loads the class, therefore the Object.registerClass is never performed meaning no link exists between the VO and Java Object. If there is no link then when the object gets past back to a Remote Object flex server treats it like a ASObject rather than the required Java Object.
This question is related to your reply. Is there some way of telling flex server not to pass final Static fields from Java to Flash? I have worked out how to do it from flash to Java using _global.ASSetPropFlags, but I would prefer that they are not sent to flash to start with.
