Hello,
is there any API to access the token during the runtime?
Is it possible to attach contextual information to a token, to create some sort of dataflow in BPMN?
For example: let’s assume the BPMN model describes a car production assembly line. The token is supposed to be the car. On each activity more parts are attached to the token.
Or are there any best practices to track dataflows over BPMN?
Are there any plans in the future, to support BPMN data objects in the BPMN engine of camunda?
The token never holds any process instance data. It should be thought of simply as an indication of a current state. Variables can be stored in a processes instances and the history of additions to them is stored independently of the toke.
So without needing the token you can simply look up the histroy of a given variable to see how and where it was changes over the course of the process.
