We invite you to try it out!
For testing purposes use the current 7.4.0-SNAPSHOT of the engine and repeat a CMMN task as often as you wish.
There also exists some documentation with an explanation how the repetition rule works and how you can use it. Just read the section about repetition rule.
Every feedback is welcome.
If you miss something or something does not work as expected please let us know.
PS: We are currently refactoring the documentation. So apologize if there is something in the documentation that does not work as usually. We are working on it.
