[Users] clustering and legend on WFS

[François BOUSSUGES]

Hello.

I'm in trainning to the INRA (agronomical national research institute) 
in France.
I create a webmapping application for display world genetic data (lots 
of points on a worldmap with attributs).
My application is build about GeoExt (and MapFish for some function) and 
geoserver.

I have some problème with two things:

- some points (on WFS layers)have the same lat/lon, for resolve this 
problem I think to use OpenLayers.Strategy.Cluster. it's work perfectly 
but when two points are clustering, there attributs (in a grid panel) 
disappear. Have you a solution to cluster my points and save the 
original information in the grid panel?

-my second problem is the GeoExt.LegendPanel, I can't display the WFS 
legend in this panel, the only thing display is the big R of my raster 
layer (bluemarbble). have you an idea?

Thank you very much for your help (and sorry for my poor english).

With my best regards
