Helo, here's my little story:
I have a TileList that's powered by an ArrayCollection with data
obtained from a DataService (via it's "fill" method). For the DS I
set autoCommit="false".
I enabled the DnD for my TileList (it has built-in DnD support) and
I also set it to allow item move, not copy.
What I'm trying to do is to re-arrange the items on this managed
collection. With the mouse, I'm dragging an item into a different
location on the grid. I wrote an event listener for the
DragEvent.DRAG_COMPLETE event, where I call DataService.commit() for
my managed collection.
What happens on the FDS side (it's actually LCDS 2.5.1): the
destination I wrote is a Java implementation. It's "sync" method
gets called, and the list of changes contain 2 items: "delete"
and "create" for the item I previously DnD-ed on the grid. There is
no indication regarding the new position in the grid for the "new"
item.
I _do not_ want to delete and create anything. I just weant the FDS
to do whatever is necessary to update it's managed collection, and
return the "OK" back to the client. I don't want FDS to call
the "fill" method again, as there is nothing new to refresh from the
database (I do not want to persist this item reordeting action for
now).
I managed to prevent the unnecessary "fill" call from happening,
using the <fill-contains-method> configuration in XML, but the end
result is the FDS does not accept the client's request, deletes the
item I DnD-ed and therefore makes it dissapearing from my grid.
Here is the log info, from the moment I filled in my grid (with 3
items) and up until my list has just 2 items, after I tried to move
the first one via DnD (this first one is the one that got vanished).
I wonder why this behavior? What's missing from what I've done?
Many thanks,
Robert
