it is possible to approve a flexi task for an other user?
I'm trying to create a Webservice which calls the nintex-webservices to approve/reject flexi-tasks.
I'm allready able to approve a flexi-task with the help of the nintex-webservices but my problem is that the Webservice which calls the nintex-workflows runs with a serviceuser. In this case the serviceuser tries to edit a task for an other user.
The response-message of the nintex-webserice-method (the method i mean is "ProcessFlexiTaskResponse2") is in this case "Invalid user".
Someone an idea?
