[Users] Added layers and permalink

[gbrun]

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
