Activiti 6 handles forms differently than Activiti 5. The built-in form properties will not work in the Activiti 6 UI. Forms are designed using the form designer and attached to a start event or a user task.
Could you let us know a Sample flow how to use Enum. Appreciate any reference documents how to use in general Activiti 6, the existing user guid for 6 or 7 is does not talk about any of these. Most of the youtube or reference material in internet talks about Acitiviti5. We are lost using Activiti6 there is no proper document.
