Тема: Re: [midPoint] Access to assignhments in message generation
Your code is OK. Just as you expected, it can be written in a little bit more compact way:
AssignmentType itemToApprove = event.getProcessInstanceState().asObjectable().getProcessSpecificState().getApprovalRequest().getItemToApprove();
PrismReferenceValue reference = itemToApprove.getTargetRef().asReferenceValue();
String oid = reference.getOid();
Class clazz = reference.getTargetTypeCompileTimeClass();
PrismObject obj = midpoint.getObject(clazz, oid, null);
body = "Выдаваемое полномочие \""+obj.asObjectable().getName() +"\"";
Especially note the midpoint object that points to MidpointFunctionsImpl containing a lot of useful methods. Unfortunately, there seems to be a fault in the notifications module preventing the getObject method from working correctly (some threadlocal variables are not set up) when called from the notification scripts. I'll fix that (MID-2373<a class="moz-txt-link-rfc2396E" href="https://jira.evolveum.com/browse/MID-2373"><https://jira.evolveum.com/browse/MID-2373></a>). Until that, it seems to be necessary to use your solution based on calling model API directly.
BTW, your requirements seem very reasonable to me, so I've added a couple of convenience methods to WorkflowEvent class (see last commit). So your code can be reduced to this one:
<bodyExpression>
<script>
<code>
import com.evolveum.midpoint.wf.impl.processes.common.*;
import com.evolveum.midpoint.prism.*;
import com.evolveum.midpoint.xml.ns._public.common.common_3.AssignmentType;
import com.evolveum.midpoint.xml.ns.model.workflow.process_instance_state_3.*;
import com.evolveum.midpoint.prism.path.*;
import com.evolveum.midpoint.model.impl.controller.ModelController;
import com.evolveum.midpoint.task.api.Task;
import com.evolveum.midpoint.task.api.TaskManager;
import com.evolveum.midpoint.schema.result.OperationResult;
AssignmentType itemToApprove = event.getItemToApprove();
PrismReferenceValue reference = itemToApprove.getTargetRef().asReferenceValue();
String oid = reference.getOid();
Class clazz = reference.getTargetTypeCompileTimeClass();
TaskManager taskManager = SpringApplicationContextHolder.getBean(TaskManager.class);
Task task = taskManager.createTaskInstance();
OperationResult parentResult = task.getResult();
PrismObject obj = SpringApplicationContextHolder.getBean(ModelController.class).getObject(clazz, oid, null, task, parentResult);
body = "Выдаваемое полномочие \""+obj.asObjectable().getName() +"\""; </code>
</script>
</bodyExpression>

Is it easier way to take it?

Тема: Re: [midPoint] Access to assignhments in message generation
It should be possible. Let event be an instance of WorkItemEvent. Then:
- event.getProcessInstanceState() is an instance of ProcessInstanceState (it maybe will be renamed to ProcessInstanceStateType in later versions of midPoint)
- in its "processorSpecificState" attribute there is an instance of PrimaryChangeProcessorState, which in turn has the attribute "delta"
- delta contains the delta that is being approved
In your case, the delta should contain the assignment that is to be added.
I'm not sure that I've actually tested this, but it should work. If not, just let me know.

Subject: [midPoint] Access to assignhments in message generation
Is it possible access to requested assignments while message generation?
