[Users] Synchronized two GridPanel with selectFeature

[François Boussuges]

Hello,
I have a question about the feature selection and the grid panel.

I have a WFS layers with a grid panel, in this layer I have an ID_SITE 
attribute.
In a second grid panel I load XML files (with Ajax), this files contains 
the ID_SITE attribute.

When I select à features of my WFS layer (on the map or the gridpanel) 
what do I do to select automaticaly rows with the same ID_SITE in the 
second grid panel?

Thank youvery much!

François
