I would add an id to the parameter name: "num.iterations.ID=something"
If your mapper knows what ID it has it can just pick up this value from the
context. But the question is:
How does the mapper know about it's ID? Is it related to the input? Thank
it can be calculated but this is
a domain specific issue.
