My client requirement is that, after selecting an item on a Select list, he can upload files and descriptions according to that selected item. The idea is to dynamically populate a group that can be duplicated, with the requested data. But as I've seen on Bonita, it doesn't seem possible to dynamically change the amount of group items. How can I achieve this? And, is there any way to consume a REST service from Bonita? Thanks.
Also, I can't find anything useful about Iterate (a practical example) on the documentation, is there any example of this?
