I would like to filter a WMS layer served by geoserver but I can't seem to get
the filter to work.
For a vector layer I can use the following just fine:
var layer = new OpenLayers.Layer.Vector("vector layer", {
...
filter: new OpenLayers.Filter.Comparison({
type: OpenLayers.Filter.Comparison.EQUAL_TO,
property: "prop",
value: "value"
})
});
I have tried using this same filter in the params and options blocks of a WMS
layer. It appears to be ignored in the options, but is not converted to a
filter in cql or something in the wms request and shows up as [object Object]
var allStreets = new OpenLayers.Layer.WMS(
"All streets", "/geoserver/wms",
{
filter:
},
{
..
}
);
thanks,
charles
