question on PlaceChangeEvent

[sri]

Hello,
We have a situation where, making a Menu selection( say startOrder )
takes us to a OrderPlace and fires a placeChangeEvent. When this
happens, the activity associated with this place is started and the
user can enter a New order and save etc. But once I'm in the
OrderPlace and I have saved my current order and I want to start a New
Order and click on the same Menu selection( startOrder ), since I'm
already in the OrderPlace, I don't get a new PlaceChangeEvent, to stop
and start the NewOrder Activity. Is there a easy( correct ) way of
solving a situation like this?

Thanks in advance..

You should either:

• clear the form once you saved (so you're implicitly already back in the "start new order" state)
  
• make a NewOrderPlace compare different to every other NewOrderPlace instance (default behavior when you don't override equals()); and of course do not use a singleton NewOrderPlace instance.
• goTo the OrderPlace with the ID of the saved order, once saved (so that going to newOrder will indeed go to a different place)

FYI, GMail uses some kind of "replace place" as soon as your mail is (automatically) saved as draft. There's no such thing in GWT though (yet!)
