Subject RE: Attribute question for Commons Digester
Date Fri, 29 Jun 2007 10:53:46 GMT
You mean:

        digester.addObjectCreate("article", Article.class);
        digester.addSetProperties("article", "id", "id"); 

Yup. I've tried that. The actual value of the id field in the XML
"_1234" is ignored and "0" is set on the Article id field instead. I
assume that this is because of the underscore in the id field.

Have you tried an ObjectCreate followed by a SetProperties?
