Re: [Geoserver-users] Feature/Attribute question - complex Feature

[Brent O. <bre...@gm...>]

The complex feature model should solve this for you. It is currently 
under development on another branch and is waiting to be merged back 
into trunk on both geoserver and geotools.

Here is some documentation on it:
http://geotools.org/display/GEOTOOLS/ComplexDataStore+project
http://geotools.org/display/GEOTOOLS/Feature+Model+Design

For a temporary solution, I would just query the edge layer for WMS. 
What do you mean by "the problem is the number of these Edges is 
variable depending on the database"?
