Hi Jon,
Good debugging! I'd like to see some clear rules about struts & bean
properties,
so here's my attempt. (Not having read the bean spec very carefully!).
1 - If you want something treated as a property you must have get & set methods
even if you won't call them both (from bean spec).
2 - Declare the get & set methods together (not necessary but good standard)
most people do get before the set.
3 - If you overload the methods keep the matched pairs together.
This is alarmimg. I figure if if follow these rules I won't hit any problems.
It seems you've discovered that it's dangerous to overload methods that are
properties. Has some-one got the time to get to the bottom of this?
cheers - Keith.
