I'm running into some trouble writing features I get from a wfs server
to a local shapefile.
I've read through the csv2shp and the query lab example pages.
I have a collection of features from:
FeatureCollection<SimpleFeatureType, SimpleFeature> features =
dataStore.getFeatureSource( dataStore.getTypeNames()[0] ).getFeatures(
query );
I build a ShapefileDataStore and createSchema using the schema I get
from the dataStore.getSchema( dataStore.getTypeNames()[0] )
when I add my FeatureCollection to the ShapefileDataStore I get an
IndexOutOfBoundsException.

I've found that if I iterate through the FeatureCollection and call
getType on one of the individual features and then use that to set the
schema on the ShapefileDataStore
that I can then store the features. I've verified that they do indeed
go out to disk and the shapes look right but all the attribute names are
null and the additional attributes aren't present.
Why doesn't the schema in the individual features match the schema
reported from the wfs dataStore?
