[OpenLayers-Users] Wipe out Map for different projection

[Heiko Schröter]

Hello,

i'am fairly new to OpenLayer so i don't know if this has been asked before.

I want to display a map in two projections which can be selected on the webpage.
EPSG4326 and EPSG900913.

But i cannot "wipe" out the old projection and reload init(projektion) with the new projection.
I've tried to do remove the layers etc. But that doesn't work.

It reloads the new projection but below and outside the <div>map</div>.
It looks like it is attached to the old (cleaned) <div>map</div>.

Is there a way to completely "RESET" the OpenLayer.Map setup or is it better to reload the page to completely wipe out the DOM ?

Thanks and Regards
Heiko

    map.setCenter(new OpenLayers.LonLat(0, 0), 3);
