Hey Freddy,
Thanks for the prompt and detailed reply.
I know about the map-related bindings as I have some extensive
Struts/Struts2 experience. However, I need to perform some logic when
binding this value. In other words, I need more than a map. As mentioned
earlier, I would like to bind to something like
setSomething(Gender gender, Double value)
When method setSomething is called I need to perform some additional
logic. I was just wondering if it's possible to bind to something like
this, as I don't want to implement a Map for such a small issue.
As I said, this is not an actual problem as I am using a Map already to
which I am binding and then calling setSomething(...) for each entry in
the Map. My question is if I have this "option" to improve my code.
