1. The html label is for labelling an input, not for arbitrary text. As has
been mentioned on this list, use a span or similar for arbitrary text.

2. Instead of ${a} + b, I think you mean ${a + b} (see
http://tapestry.apache.org/property-expressions.html)
3. I'll join Thago in "slamming" you. Tapestry's live class/template
reloading makes it just as simple to put this in a java class as it is to
put it in a template. It then becomes easier to test and re-usable.
