There is a Box with a collection of Loans. From another (non FSD) process, a specific loan is updated in the database. When the box is loaded within the Flex client, this loan still has the old value. See the following scenario: Retrieve Box: The Box and Loans are displayed Update a property on one of the Loans in the database. Retrieve the Box again. The BoxAssembler.getItem() returns the Box, including the updated Loans collection. This is OK. However, the Flex client "result" property from the BoxService contains the previously loaded value. We have the Box.as object declared with [Managed] [RemoteClass(alias="foo.bar.vo.BoxVO")] public class Box { ... public var loans : ArrayCollection = new ArrayCollection(); ... } How do we get the updated Loans collection from assembler to client? Isn't FDS supposed to handle this?
