[OpenLayers-Users] I'm stupid?

Thu Jun 26 09:20:45 EDT 2008

Hy list, I start With OL " dais ago :S and I don't know javascript :SS!!
But I start to developing some simple application... And at the first time
was easy to  start (copy paste the code)...
But now I have some problems with a gml layer, and I have the impression tha
OL it's not more stable (maybe because I don't know javascript)...
It's my 5 or 6 email to the list asking for a the same question. Problem
with GML layer pan, they change the coordinates?!!!
I start to play with projections and now the problem it's bigger.
When I change the base layer... the map changes too!!!
I don't understand anything:S this is the code i write:
