I would like to create a workflow that only gets started if the initiator belong to a given sharepoint user group (called "Assistant").
I have already created the Initial Nintex Form as well as the Nintex Workflow associated to a SharePoint list.
The idea is that only the users belonging to the "Assitant" group have the possibility to start the workflow. The first "solution" I figured out was to start the workflow and then check whether or not the initiator belongs to the Assistant group (calling a webservice to retrieve the list of users in the Assitant group and then comparing the collection to the initiator, shown below, GetUserColectionFromGroup,...).
This solution is not the proper one since the workflow starts and then terminates depending on the initiator.
Can anybody help me?
