Hi, 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.
