    Description

      Scenario:
      Multiple executions exist during the attachment creation for a process instance.

      Example API call:

      TaskService taskService = processEngine.getTaskService();
      taskService.createAttachment(uploadContentType, null, processInstanceId, uploadFileName, description, fileInputStream);
      

      Current behavior:
      An exception is thrown:

      org.camunda.bpm.engine.ProcessEngineException: processInstances does not have 1 elements

      Expected behavior:
      The attachment is created successfully.

      Hints: The exception is caused by the class CreateAttachmentCMD

      A workaround is to provide an empty String instead of null as taskId but then the operationLogManager is never called (the task of the taskId is never validated).
