Jeff, Thanks for the response. I've sent the details (my data-management-config.xml, and debug output) to you in a private email, as the information is sensitive.
The stack overflow was occuring after the call to fill, but before the result came back. I have adjusted my destinations to only have one side of the bi-directional associations set to lazy=false, and that has fixed the null value, as well as the stack overflow. Thanks for that tip. I was under the assumption that it would only serialize the same object once even if it was referenced from multiple places in the object graph. thanks, Thunder --- In flexcoders@yahoogroups.com, "Jeff Vroom" <[EMAIL PROTECTED]> wrote: > > Hi Thunder, > > > > I am not sure about the stack overflow though usually I don't recommend > using lazy="false" on both directions of a bi-directional relationship > since it can end up sending the same data more than once to the client > which results in inefficiency.
