Hi,
I have a layer group, let's say "group_1", where all the sub-layers are
queryable. The group layer is also effectively queryable and GetFeatureInfo
works if I use &QUERY_LAYERS=group_1. The problem is that the group layer is
not announced announced as queryable in the GetCapabilities
<Layer>
<Name> group_1</Name>
<Title> group_1</Title>
...
<Layer queryable="1" opaque="0" cascaded="0">
<Name> sub_layer</Name>
....
I would like to see it as:
<Layer queryable="1">
<Name> group_1</Name>
<Title> group_1</Title>
....
<Layer queryable="1" opaque="0" cascaded="0">
<Name> sub_layer</Name>
....
Without queryable attribute I can't make GetFeatureInfo to work when I am
cascading it with Geoserver. By reading the WMS 1.1.1 standard I feel that
GeoServer is behaving as it is supposed to work: if the layer is not announced
to be queryable then it is not queryable. I can't find any mention in the WMS
standard that a group layer should behave in a different way than the normal
layers.
7.1.4.6 Layer Attributes
A <Layer> may have zero or more of the following XML attributes: queryable,
cascaded,
opaque, noSubsets, fixedWidth, fixedHeight. All of these attributes are
optional and
default to 0
7.1.4.6.1 Queryable layers
A Layer is said to be "queryable" if the server supports the GetFeatureInfo
operation on
that Layer. A server may support GetFeatureInfo on some of its layers but not
on all. A
server shall issue a Service Exception (code="LayerNotQueryable") if
GetFeatureInfo is
requested on a Layer that is not queryable.
Is there any way to add the queryable="1" attribute to a layer group?
