OK, thanks Andreas.

I'm quite surprised to be the first to find this problematic...
Never mind, it's not very important right now.

I don't need any conversion, in my case, since i'm working with EPSG 4326.
What i still don't understand, is how to apply map.zoomToExtent ? Can i do
it without writing javascript code. Is there a tag, a widget that does it ?
Or shall i write a piece of javascript code ? And if yes, where ? Any idea ?
Any pist ? Just to start with ?
I'm just beginning with MapBuilder (i was planning to use directly OL,
before i realised mapbuilder's possibilities and got seducted), and i'm
still not very at ease with Mapbuilder's structure and mind.
Thanks a lot,
Jean
