Basket MAP : unable to cancel perimeter edition / loosing perimeter
We encounter some behavior problems with the basket perimeter edition.
It seems that the preview map (and the saved perimeter) is binded to the edition popup map. This leads to "non-natural" UX behavior.
The main problem is that we cannot "cancel" perimeter edition.
We have described 4 use cases: all 4 start with a user that sets a perimeter, saves, then go back to edit popop. Then:
1) Do not change perimeter and save
2) Do not change perimeter and do not save (cancel)
3) Change perimeter and save
4) Change perimeter and do not save (cancel)
Cases 2 and 4 fails, as the previously defined perimeter is lost on cancel.
This is a big issue for us, as we have users selecting dozens of WFS perimeters or drawing complex polygons (then eventually loosing it all).
