I'm creating a new webmap in version 4.5, and am setting the initial extent by using the center+zoom properties.
Works all nice and good, but then when i later try to get the extent, mapview.extent returns null.
Apparently when you use center+zoom, the extent then never gets set?
This sounds like a bug to me.
I need those extent values for some other calculations. Any idea how to get them or calculate them?
