I think the main reason for only allowing Strings (and I thought booleans also), are the setter methods: if Struts receives some String (from the http response) and wants to set the property of the according server-side bean, it has no way of knowing (a) which type is required for the setter, and moreover (b) how to do the conversion. And allowing for getter methods to return different types than the setter methods require, seems to be incompliant with the javabeans spec (although I'm not sure about that) > Building 'html:link' tags seems particularly awkward when > parameters are > required. > The Map approach seems ugly since it requires an extra method > on every bean > which > goes through a population process on some object that > implements 'Map'. > Why was the tag-lib attribute interface not extended in some way? I don't know 'the Map approach'... You're always welcome to enlighten me with some url :-) But I agree that html:link could have nicer design for GET parameters (nested tags would be nice... is this possible with taglibs?
