As part of reporting/dashboarding functions in our software, I want to provide a "process instance state" report that can be accessed via REST services that we publish. To that end, I get the "current task" for a process instance:taskService.createTaskQuery().processInstanceBusinessKey(processInsta

Hi John,

Can it be assumed that, while a process instance is active, there is always at least one active task that will be returned by this query?

Is there such a getter?

Type of the task is stored in the model/definition.

Hmmm, OK. So how would one find the model, find the task definition, and extract the task type? I realize that I could load the XML directly from its resource and parse it myself. Looking for a shortcut. Do I need to go at it from the Deployment interface?

taskService.createTaskQuery() only returns user tasks. You would need to use runtimeService.createExecutionQuery() to get all running executions of a process instance. Every execution has an activityId property and that can be used to retrieve the Bpmn element with all the type info etc. RepositoryService.getBpmnModel gives you the BpmnModel of a process definition id and then you can use bpmnModel.getFlowElement(activityId) to get the specific Bpmn element and with that all its information.

Best regards,
