> If I do a solution set match and there is no corresponding entry in the solution set index a RuntimeException is thrown and the job fails. Therefore the initial solution set must already contain every element which will be in the final solution set.
> I'm not sure if this is a real limitation, but I find it inconvenient. When I was playing around with the workset connected components I couldn't just use parts of my test data, because it resulted in a solution set join where records couldn't be matched.
> I just wanted to think out loudly here. Did anybody else find this inconvenient? What alternative should we provide?
