Subject RE: Attribute question for Commons Digester
Date Fri, 29 Jun 2007 11:05:33 GMT
Also, does the plugin class need to implement a specific class? It
doesn't look that way in the examples, and there doesn't appear to be
any way to get the Digester to call a specific method in the plugin
class.

I have the feeling I have misunderstood something here..

Yeah, I didn't notice the "_" (or read the rest of the request).  You'll
need a custom rule here to convert that value, otherwise SetProperties
would work (and you don't need to specify "id"/"id" because it'll match
the properties to the attributes if they match exactly).  Why the
underscore anyway?
