Well I would do it in a script-task and use groovy as the language. That way you could do it in java. (which I prefer). Do manipulations you need and then set process variables by calling execution.setVariable(“moreThan10Days”, true); for example. Then make a juel-expression where you need it for example as a condition on a gateway to choose which path to go in the process.

I’ll post some ideas here…
