Updating a BPROC process variable directly from a service in the core

Support
#1

I´d like to know how to update a process variable from a SERVICE in the CORE

        //TODO UPDATE PROCESS FORM FROM CORE ::
    ProcessInstanceDataQuery processInstanceDataQuery = bprocRuntimeService.createProcessInstanceDataQuery();
    ProcessInstanceData processInstanceData = processInstanceDataQuery.processInstanceId(processInstanceId).singleResult();
    processInstanceData // I WANT TO UPDATE A PROCESS FORM VARIABLE FROM HERE
    /*processInstanceData.process
    bprocRuntimeService.process*/

I would also like to know how to send the processInstanceId from the modeler to a service task.

also, is this the best way to get the current process instance data of the current form?

ProcessInstanceData processInstanceData = bprocRuntimeService.createProcessInstanceDataQuery()
            .processInstanceId(processFormContext.getTaskData()
                    .getProcessInstanceId()).singleResult();

Take a look at the setVariable method in the BprocRuntimeService: com.haulmont.addon.bproc.service.BprocRuntimeService#setVariable

Your service method may have a string parameter called executionId. When you define an expression for the service method parameter value in the modeler, pass the execution.id there and check the “is var” checkbox.
