I have a problem where when editing features from a wfs vector layer. After some changes are made to the geometry, the feature redraws itself and the changes are lost.
Usually the problem occurs more often if a feature is huge and has many vertices. Also if the user pans and zooms in/out a lot.
My guess is that the browser (FireFox 18) "looses the cache" or something and therefore does a new request to the server and the feature is rendered and the changes are lost.
Is there a way to solve this or is the solution to "save often"?
