I've spent some time exploring the Expense Report example. The current PlacePickerView used in Roo M1 is only selecting Places that have already been generated and handled somewhere else.
The more I look at the navigation/selection tree on the left, I feel it should be subject to an Activity. I felt that the navigation should be fire PlaceChange events, should listen to RecordChange events and should, in general, not access RequestFactory directly but through a Delegate. Can you clarify what direction Roo is going to take?
