Hi Jody,
(using version 2.6)
Yes, you're right, the same works like this :
filter = CQL.toFilter("status LIKE 'ON'");
map.addLayer(featureSource, null);
Query myQuery = new DefaultQuery(myLayerFT,filter);
map.getLayer(myLayer).setQuery(myQuery);
And, as you said, this is probably a better way.....
Thanks !
Fred.
