On trunk this is happening as a result of making GetFeatureInfo work with
complex features (http://jira.codehaus.org/browse/GEOS-4351),
but it should never happen when working off standard data sources.
Where is your layer data coming from? A custom data store?
I've cc'ed Niels, the author of the change that's resulting in the
exception you're seeing.
Niels, wondering if the following test:
if (! (collection instanceof SimpleFeatureCollection)) {
//put wrapper around it with layer name
Name name = new NameImpl
(layer.getFeature().getNamespace().getName(),
layer.getFeature().getName());
collection = new FeatureCollectionDecorator(name,
collection);
}
would not be better expressed as:
collection.getSchema() instanceof SimpleFeatureType
