Hello All. @Andreas : yes for the moment this is exactly what i use (same WFS server, enumerated feature list), but this breaks the functionnality i want to have "if i deactivate a layer on my map, the grid should be updated accordingly." I don't want to add extra layer switching menu, the user should use the standard OpenLayers/French Geoportail layer switcher.
@Matt : thank you for the plumbing tip. From my point of view, the design would me more at the Vector level : could not it be possible to write a Vector implementation that is a Composite (like the design pattern) of several Vector instances ? 2010/5/18 Andreas Hocevar <[email protected]> > Hi, > > if your WFS supports multiple feature types per request, you should also be > able to configure your OpenLayers vector layer with a comma separated list > of feature types.
