Thanks all for your assistance - we've now identified the cause of the
problem!
The DepthArea feature is defined in our GML Application Schema with a
single geometry property (multiplicity unbounded). However, our
app-schema mapping file takes geometries from three spatial columns
(points, lines, polygons) in our PostGIS database and maps them to this
single geometry attribute in the GMLAS.
This worked fine for a WFS request, but appears to fail for a WMS
request. However, when we changed our mapping to be 1 to 1, i.e. a
single spatial column to the single geometry attribute, the WMS
successfully gave us a PNG image.
It would appear that GeoServer WMS does not support the rendering of a
feature's geometry when it is mapped across by App-Schema from multiple
geometry columns. However, we have decided that a suitable workaround
for us is to define multiple geometry properties in our GMLAS, one for
each geometry type, and then simply perform multiple 1 to 1 mappings
between a PostGIS geometry column and its corresponding property in the
GMLAS.
Many thanks again for your assistance :-)

Hi,
You have two troubles: First you have not used WMS before and you feel
not sure about how to make correct requests. Second, you are using some
complex feature type that may make some special troubles.
Try to cut your cake and make a new layer with simple data from your
area. For example the World borders shapefiles are in EPSG:4326 and
should be good for you
http://thematicmapping.org/downloads/world_borders.php
Once you have made your system to show images for you from this dataset
you know that pretty much is OK. After that change into your own dataset
and see what happens. If it fails, you can do more detailed questions
for us and we can concentrate to what is essential. It will take some
time to prepare the reference layer, but it will save more.

Andrea, Ian, Rahkonen and Rini, thank you all for your suggestions. I'm
now using the following WMS request:
http://localhost:8080/geoserver/wms?
SERVICE=WMS&
REQUEST=GetMap&
VERSION=1.1.0&
WIDTH=459&
HEIGHT=353&
LAYERS=sprint21:DepthArea&
TRANSPARENT=TRUE&
FORMAT=image/png&
BBOX=-1.304114,50.724729,-1.040936,50.817929&
SRS=EPSG:4326&
STYLES=
I believe this is the correct WMS request following Ian's guidance -
I've also set STYLES=, which should make the layer use its default
style. I've checked in the GeoServer Web Admin page - my DepthArea layer
has "polygon" as its default style, and this SLD just specifies that
polygons should be rendered in a certain colour - there are no complex
rendering rules based on the feature's attribution, so I don't think the
bounding box error is being caused by an invalid styling.
Can you think of anything else I can try, or any other configurations I
should check that may resolve this bounding box issue?
Best Regards,
Ryan

Hi Ryan,
I suspect it has something to do with your style.
Is it referring to some properties that don't exist in the complex
feature type?
This might help:

Ok, so we have a filter visitor in app-schema (thus, you are using
complex features) that bombs
when dealing with the FastBBOX filter, an custom optimized BBOX filter
implementation that
speeds up (significantly, at least on fast data sources) rendering.
Possibly something for Ben and Rini to look at?
Cheers
Andrea
