Hi,

How can I perform query such as: which objects are within specified distance (e.g. 10km) from a certain point? I tried CQL _expression_ in Table view in the form of DWITHIN(ATTR1, POINT(X Y), Z, kilometers), but the geometry attribute of the object does not exist in Table view, so the query returns nothing. Similar thing happened with other operators. Is it possible to perform spatial query to select objects from the table that are in some spatial relationship with a given object?
