Pete- Thanks for your help...I've finally identified the problem (but still not the solution). Although I did have a reference of my siblingPojo back to my MainPojo, commenting out that code did not solve the problem. However, my SiblingObject has an attribute that is part of a class with static variables. So to give you an example, my SiblingPojo has an attribute like this:
private Status status = null; When I construct my data objects in the back-end, I set this variable using it's own static data: siblingPojo.setStatus(Status.CONFIRMED); Here's the Java code of the class that the serialization is hanging up on. This is a pretty standard j2ee design pattern. You'll see that I only have a private constructor. This is what ensures that the variable data will be constant throughout the app. If I were to add a public constructor, the class would not compile (since my variable 'type' could technically never get instantiated)...I'm guessing the serialzation is hanging b/c there is no public empty constructor? have you ever come across a situation like this before? Thanks again for your help. public class Status{ private final String type; private Status(String type) { this.type = type; } public String toString() { return type.toString(); } public static final Status UNASSIGNED = new Status("UNA"); public static final Status ASSIGNED = new Status("ASG"); public static final Status ACKNOWLEDGED = new Status("ACK"); } --- In flexcoders@yahoogroups.com, "Peter Farland" <[EMAIL PROTECTED]> wrote: > It sounds like you might be in an infinite loop somewhere on the > client... a common way to get into such a loop is when processing object > graphs with circular references. > > From your MXML code listing below (i.e. it shows direct binding of the > RO result as a data provider) I don't see that you're doing any > recursive processing of the result so I'd propose that you've discovered > a bug with DataGrid when bound to object graphs that have circular > references. > > How, you might ask, would you have a circular reference in an object > graph from a RemoteObject result?
