I am getting this error during deserialization: RangeError: Error #2006: The supplied index is out of bounds. The error occurs in AbstractMessage.as when it attempts to read input of timestamp.
After that my fault handler gets this error: faultCode:Server.Acknowledge.Failed faultString:'Didn't receive an acknowledge message' faultDetail:'Was expecting mx.messaging.messages.AcknowledgeMessage, but received null' It appears to be happening as a result of an ArrayCollection coming back from the server. Is it necessary to create custom classes to handle serialization of ArrayCollections with custom objects as shown here (http://iamjosh.wordpress.com/2007/12/12/serialization-of-custom-collections-for-flex-data-services/) ? I've also followed the serialization recommendations here(http://www.brooksandrus.com/blog/2008/03/25/flex-air-serialization-lessons-learned/) with no luck. Can you have non-empty constructors on the java side? Thanks for your help!
