Hi! I'm coming back with more informations. So, I tested WMC instead of Permalink: that's just great! For this, I was inspired by the OL example, and also by this previous message: http://www.mail-archive.com/users@openlayers.org/msg05112.html
So, the issue I'm now encountering concerns WFS layers. In fact, WFS layers are not saved in WMC format. I think it should be normal: WMC only concerns WMS layers, doesn't it? Is there a way to save WFS layers with WMS layers in WMC format? I was thinking to get all the WFS layer names from a permalink, and then to add them in the WMC created. Does anyone know if this method could work? Geoffrey On Mon, 22 Aug 2011 15:18:18 +0200, gbrun <gb...@myopera.com> wrote: > Thanks for your reply!
