In a web application, we usually convert the request params from String (or String array) to Beans. All web frameworks do that.
Is string conversion a topic of Web beans spec?

A conversion workflow has usually 3 phases:
1 - inspect the property type: String, Date, Number, beans
2 - do the conversion: "'1" to 1, "01/01/2009" to Date, etc
3 - inject the converted object according the request name: "", "person.age", etc

Who would have do this conversion?
