Hi Robert/Edgar. I sent in a patch a while ago which I think would solve your problem. [It was a while ago, so my memory might be misleading me].
There was no response; I meant to follow up but have been kind of busy later. See http://marc.theaimsgroup.com/?l=jakarta-commons-dev&m=102150414316796&w= 2 I'm not claiming that the patch *should* have been added; there may well have been reasons not to.. As mentioned in the referenced email, there are a couple of solutions that don't involve modifying digester: (a) write CallMethodRules to map attributes to setter methods instead of using SetProperties. (b) writing an XXXBeanInfo bean properties class which specifies attribute-name -> setter-method mappings (see java beans documentation).
