Hi Werner, Thanks for your great work!
I just downloaded Castor 1.3.1 and found some problems, 1. I define a <field-handler>, it can be used in only one <class/> 2. if the <field-handler> is defined in a mapping file, and this file is included by another main mapping file, marshal the java bean will throw exception.
