After a fresh cup of joe, I think I've figured it out. Because I've retrieved the underlying object graph from FDS, it is still under the control of the DataService's propertyChange event. This gets fired everytime a property changes in the tree. The solution is to call DataService.releaseItem(Tree's DataProvider) before you manipulate it.
Now, when I save the changes to the tree, I'll just make the FDS call to get the object graph, then re-assign it to the object graph from the tree. I'll also need to check the row version to see if anybody else has modified the object. --- In flexcoders@yahoogroups.com, "box110a" <[EMAIL PROTECTED]> wrote: > > I have a tree that is populated with an object graph from FDS.
