I don't follow you; I'm explaining what Tapestry does. Well, I guess its this: if you use the property inside Java code, then create an abstract getter and you're done. If the property is only used inside the .page file (and/or the HTML template), then use a <property> element. Generally, the latter case only applies to properties used to hold the current value of a For loop.
