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.<br>
<br>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?<br>
