[Geotools-devel] Re: new FeatureType//Attributes

[David Z. <dz...@re...>]

Dave, 

The class in question is NEW (it was added), and is intended for use
with the length function, and takes an AttributeType. This means that
there is not a defined way to set a new attributeType (ie. the
FeatureType is not there) ... so an appropriate exception is thrown.

Please use the old implementation
FilterFactory.get...(FeatureType,String) is you wish to modify the
Attribute type.
