Hello,

i already got a task by starting a process instance (http://www.activiti.org/userguide/index.html#N13876).
But I am missing some fields, that won't get set to the task.
I want to set the "dueDate" field for the task.

Json looks like this:
{"dueDate": null}
Url:
/activiti-rest/service/runtime/tasks/2250

When I try to update it, the server throws:

org.restlet.ext.jackson.JacksonRepresentation getObject
WARNUNG: Unable to parse the object with Jackson.
org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "dueDate" (Class org.activiti.rest.api.runtime.task.TaskActionRequest), not marked as ignorable

But I am able to close the task using the same url but the json: {"action": "complete"}
After looking into the docuemntation (http://www.activiti.org/userguide/index.html#N14412) I thought that would be the right way to set a "dueDate" and/or other field-Values.

Am I missing something?

Thank you for any input.

You should use a PUT instead of a POST.

Best regards,
