Add variables back to workflow from job worker

Camunda 8 Topics Discussion & Questions

Hi,
Is there a way to add variables from a job worker back into the workflow via the job worker?
For example, I tried this, but it doesn’t work:
List orderedOptions = orderedOptionsClass.getOptions();
job.getVariablesAsMap().put(“orderedOptions”, orderedOptions);

Thanks,
Ken

Hey @ken

you can complete a job with variables, see in this example https://docs.zeebe.io/clients/java-client-examples/data-pojo.html the last line of the handler.

Hi Chris,
(@Zelldon)
I appreciate the response.

I tried your solution. I might be doing something wrong, but so far I don’t see what. (I do this kind of stuff very often with Camunda.) The variables passed in when starting the workflow instance, but not the ones passed in from the job. I use the Spring/Java client.

@ZeebeWorker(type = "get-ordered-options"):
public void handleGetOrderedOptionsJob(final JobClient client, final ActivatedJob job) {
    try {
        logJob(job);
        client.newCompleteCommand(job.getKey()).send().join();
        Map<String, Object> variablesMap = job.getVariablesAsMap();
        String orderId = (String) variablesMap.get("orderId");
        ...
        Map<String, Object> map = new HashMap<>();
        map.put("orderedOptions", orderedOptions);
        client.newCompleteCommand(job.getKey()).variables(map).send();
        ...
      }

next job worker

@ZeebeWorker(type = "set-option-values-in-request")
public void handleSetOptionValuesInRequestJob(final JobClient client, final ActivatedJob job) {
    try {
        logJob(job);
        client.newCompleteCommand(job.getKey()).send().join();
       ...
        Map<String, Object> variablesMap = job.getVariablesAsMap();
        List<Option> orderedOptions = (List) variablesMap.get("orderedOptions");
        }

This job recognizes before even starting that the “orderedOptions” variable it is not there. orderedOptions is an input collection on a multiinstance subprocess. I am running the jobs inside the intelliJ debugger. (Won’t be able to get back to this until Monday.)

Hi Chris,
(@Zelldon)

Never mind. I figured out what the problem is. Beginner’s mistake.
I had an extra newCompleteCommand statement earlier, too early.

client.newCompleteCommand(job.getKey()).send().join();

and later this.

client.newCompleteCommand(job.getKey()).variables(map).send();
