I have built a number of forms using the infopath/nintex combo but am still fairly new to it all. In many of these forms I've configured the Request Approval workflow action by following the guide in the SDK (e.g. setting up the GetRunningWorkflowItemsForCurrentUser, etc.). I am trying to find out the differences between all the task types available but have not been able to find any information on this. Does anyone know what the main differences are? What advantages are there to use one over another? If anyone can shed some light on this or can tell me where to find more information on this I'd really appreciate it.
