Hi together,

in the Camunda Modeller you can specifiy for an external task an input variable as list type.
Following there is an example.

variableFoo": {
                "type": "Object",
                "value": "rO0ABXNyABNqYXZhLnV0aWwuQXJyYXlMaXN0eIHSHZnHYZ0DAAFJAARzaXpleHAAAAACdwQAAAACdAABTHQAAUZ4",
                "valueInfo": {
                    "objectTypeName": "java.util.ArrayList",
                    "serializationDataFormat": "application/x-java-serialized-object"
                }
            },

How can we handle this in an not “JVM” technology? And transform this also back?

Looks like ArrayList does not get transformed into a string…

easy workaround for you: use SPIN JSON Array:

spinArray
spinArray1196×707 36.9 KB

and then your Fetch and Lock will look like:

Request:

{
  "workerId":"aWorkerId",
  "maxTasks":2,
  "usePriority":true,
  "topics":
      [{"topicName": "myjob",
      "lockDuration": 1,
      "variables": ["myList", "myjson"]
      }]
}

Response:
