Hi all,
first of all I wanna congratulate you for the great work and the new adventure.
I come from a project where Activiti was choosen as the BPM suite to support business processes.
Switching to Flowable i’m studying the new UI of Flowable V6.
I’m experiencing an issue. I’m adding a GROUP to the Assignments section of a User Task.
When I try to log in the Workflow Application with an authenticated user of that group, I can’t find the right “matching tasks” (the result is the same using the Identity store or the Fixed Values).
The platform works correctly when I use the ‘Candidate users’ or ‘Assigned to single user’ section.
So you’ve added 2 candidate groups to a user task. Started the process instance in the Flowable Task UI App. Logged in with a user that is a member of one of the candidate groups. And there is no task in the visible in the Task App?
Just to make sure; did you select the correct filter?
Yes. But when I select “Task where I am one of the candidates” I get the following exception.
