does BPROC addon has something like Model Elements Editor like BPM addon has, in order to add custom service tasks with own stencils, or group them into new group?
(bproc trial expired had no time to check )
If not, is it still possible to add custom service tasks?
No, in BProc custom elements are not implemented. However, there are mechanisms that you can use instead.
For example, for service task, when you select a Spring bean from dropdown list, UI elements to edit service methods parameters are displayed - you can configure service task there. See description and screenshots the Spring Bean Service Task section of the documentation.
When you select a JavaDelegate service task, then UI controls for managing JavaDelegate fields are displayed.
So you can view and configure properties that have ābusinessā names.
For user tasks, if you need to do a custom assignment, you can do it using the UserProvider. Another option is to use predefined task listeners, that may do an assignment or whatever you want when the task is assigned or completed. We donāt have a separate documentation for it, but you can get an idea from Flowable documentation.
We keep an idea of ācustom elementsā in mind but donāt have specific plans for its implementation yet.
