Andrea,
Sorry for the duplicate email, forgot to reply all :/
Thanks so much for the response. I am still a bit confused. I am using
the following SLD for KML output as a simple test:
<StyledLayerDescriptor xmlns="http://www.opengis.net/sld";
xmlns:ogc="http://www.opengis.net/ogc";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="1.0.0"
xsi:schemaLocation="http://www.opengis.net/sld
StyledLayerDescriptor.xsd">
<NamedLayer>
<Name>cite:mylayer</Name>
<UserStyle>
<Title>My Layer</Title>
<FeatureTypeStyle>
<Rule>
<PointSymbolizer>
<Graphic>
<Mark>
<Fill>
<CssParameter name="fill">#ff0000</CssParameter>
</Fill>
</Mark>
</Graphic>
</PointSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
This SLD comes the KML styling documentation here:
http://docs.geoserver.org/2.3.2/user/googleearth/kmlstyling.html#kml-styling-sld-structure
Shouldn't that work?
That SLD throws the same exception:
java.lang.NullPointerException
at
org.geoserver.kml.decorator.PlacemarkStyleDecoratorFactory$PlacemarkStyleDecorator.setLiveIconStyle(PlacemarkStyleDecoratorFactory.java:259)

org.geoserver.kml.sequence.SequenceList$GeneratorIterator.<init>(SequenceList.java:29)
at
org.geoserver.kml.sequence.SequenceList.iterator(SequenceList.java:63)
Sorry if I am missing something obvious, and thanks again for the
quick response.

What NetFlow Analyzer can do for you? Monitors network bandwidth and traffic
patterns at an interface-level. Reveals which users, apps, and protocols are
consuming the most bandwidth. Provides multi-vendor support for NetFlow,
J-Flow, sFlow and other flows. Make informed decisions using capacity planning
