I am trying to get my WFS server to return a filtered set of results (to
avoid browser overload). I had previously been sending a FILTER param in the
url - but now this is breaking because of the fact BBOX and FILTER are
mutually exclusive (tickets #1430 and #1113). I attempted the patch in #1430
but it did not seem to work for me.
I have been attempting to instead use the Openlayers.Filters - but it is
just returning the whole of the WFS dataset (unfiltered). I was under the
impression that you could use an Openlayers Filter to filter the data (as
well as apply a style). Having checked the documentation it looks like only
a GeoJSON layer has the option of adding a filter - is this true and if so
is there any plans to include this v. useful functionality in the WFS layer?
Alternatively are there any plans to fix the FILTER/BBOX error?
Many thanks
Stuart
