Hi Tim, About your solutions : 1) Multiple layers --> At first, that's what I did. They were all hidden from the layerswitcher and I had a dummy layer controlling their visibility. That was working well, but then I thought on type of data should always be displayed in only one layer. I mean, I want to have one road layer to deal with, not 4 and a dummy one. It's simpler that way, it think. 2) Configure your server --> You're right about my server(s), but not the ones I do not control. I use mapserver, so I could easily GROUP my 4 layers in my mapfile and request the group name instead of changing typenames, but what about servers I don't control ? Well, in the end I just thought "hey, this might be better to have only one OL.Layer than 5" so I wrote it.
