map.getCenter() is always null for Web maps

I'm trying to obtain the center of the map but it's always null. How do I go about doing it when using the Web view?

Start at the map.getCenter() entry point and trace how it behaves for the Web view implementation. Reproduce the null result with a Web map and compare the behavior with the other map providers; done means the center can be obtained or the limitation is clearly documented.
