I am using castor-xml-1.3.1 and castor-core-1.3.1
Please let me know if any solution or any workaround is there?
I would like to do Unmarshalling from a xml file generated through Castor
Marshaller. Here it is I get the InstantiationException for List even though
in all my mapping files it has collection attribute as arraylist
I could see a bug 1175 for Validation Exception while unmarshalling a Map
having collection as value. Is it resolved in the 1.3.1 version?
