             Summary: Support for BPMN call activity
                 Key: SYNCOPE-1020
                 URL: https://issues.apache.org/jira/browse/SYNCOPE-1020
             Project: Syncope
          Issue Type: Improvement
          Components: core
            Reporter: Francesco Chicchiriccò
             Fix For: 2.0.3, 2.1.0


From the [Activiti User Guide|https://www.activiti.org/userguide/#bpmnCallActivity]:

{quote}
BPMN 2.0 makes a distinction between a regular subprocess, often also called embedded subprocess, and the call activity, which looks very similar. From a conceptual point of view, both will call a subprocess when process execution arrives at the activity.

The difference is that the call activity references a process that is external to the process definition, whereas the subprocess is embedded within the original process definition. The main use case for the call activity is to have a reusable process definition that can be called from multiple other process definitions.
{quote}

It is currently possible to create more process definitions (besides the default {{userWorkflow}} by empowering the REST endpoint

{code}
PUT /workflows/{anyTypeKind}
{code}

The new process(es) defined can then be called from the main {{userWorkflow}} via the {{<callActivity/>}} element(s): the main advantage is that, by doing so, there are no more problems about the process definition versions, as they only apply to the main process (e.g. {{userWorkflow}}).

What is currently lacking is:
# proper management for getting all available process definitions
# proper handling for initial loading of several process definitions from XML files
# proper editing features from Admin Console

as all the items above only consider the possibility that a single process definition is available.
