You're describing the behaviour of
java.beans.Introspector.getBeanInfo(), which Jess uses. This method in
turn just implements its interpretation of the Java Beans
specification. The Spec is mute on this question, as far as I can
tell. It's easy to see how the getBeanInfo() method could get confused
and give up.
If you really need to do this, and you can't get by using a method
like setValFromString(String) instead, then you'll have to implement a
beanInfo object to describe the properties. getBeanInfo() (and thus
Jess) would then use the explicit description of the properties in the
BeanInfo object instead of looking at the method names and trying to
figure things out. it's pretty easy to do this using the
SimpleBeanInfo class as a base class.
