<br><font size=2 face="sans-serif">There are 8745 records in the database.
That is why I tried to use the cluster strategy in the first place without
success because of the error pointed out by Maxime.</font>
<br>
<br><font size=2 face="sans-serif">So I tried with a smaller dataset and
the wfs layer and the cluster strategy works perfectly.</font>
<br><font size=2 face="sans-serif">It's still doesn't work for the "big"
dataset. So I guess there a too many records. Even with the cluster strategy
it doesn't load.</font>

work for 8745 records requested from a shapefile or postgis?</font>
