You can do stuff like
@Inject public ConcreteCommand2(SomeService service,
@Assisted(Constants.FIRST) String runtime1,
@Assisted(Constants.SECOND) String runtime2) {
...
}
I've uploaded the modified example http://pastie.org/698555. If you
have a large number of params it is not pretty. Alternatively you may
try String[].
