Subject Setter in action triggers twice. Bug?
Date Thu, 16 Jul 2009 15:08:54 GMT
Hi!

I am wondering, why setters for cmd and id fields @ my Person action (see
below) is called twice. For example, when browser requests
/person-aaa-bbb?dum=ccc , this gets stdout-ed :

example.Person@113981b 18061339
setCmd ]aaa[
setId ]bbb[
setCmd ]aaa[
setDum ]ccc[
setId ]bbb[
execute

I know setter is just a setter, but this thing is really annoying me :) -
definately this kind of behaviour is undesirable. Any thoughts?
