Batch tokens using multiple groups

[jeremy_r]

When using the Batch activity in a process flow, it is possible to group tokens by a single attribute. However, you can only group by one attribute at a time, whereas I have encountered situations where it would be helpful to group by multiple.

This question has an answer that suggests a workaround of combining multiple labels into a single string. The workaround works, but it is very far from ideal.

Your request enhances a software tool and make it more complex. There are other processes you can build to achieve the same with more activities. I would use under such conditions an approach to evaluate a list and collect a batch in a sub flow structure. I know such a process structure doesn’t look anymore clean and simple as a single activity, but if you have to document a logic, then a set of more activities makes it easier, because you can refer to the process flow activities visual logic.

If you put all your attributes in an array, you can batch by that array; each unique combination of values will be batched together. List Partitions can also use array values.

BatchByArray.fsm

The Batch UI doesn't seem to display Array values very well. I'll add a case to the dev list about that.
