Update: it works!
It was the preserveViewport thing. I don't know what I did wrong the
first time.
Thanks alot!
That leaves me with 1 problem: I have a link "show all mini
maps" (shows the mini map to each step).
This link calls a function that loops as many times as there are steps
for the route. On every loop it calls my "show_mini_map" function.
I don't know if this is going to fast for the API, because all the
maps end up with a grey screen saying "zoom leven to high for this
area" (it's not, definitely)
and the marker I usually set is wrong too. If I load them seperately
they all work (showing single steps and showing all steps use the same
function,
so it's not a code-problem I think).
Does anyone know something about this issue?
Oh and one more question, is there a way to tell
mini_map.setCenter(new GLatLng(lat,lon),zoom_level); to use the
highest available
zoom for that area? That would be great.
Thanks for your help.
