Got to implement a seq. workflow based on http://msdn.microsoft.com/en-us/library/office/dn584771(v=office.15).aspx#bm3
Notice: My Entity Type is "ListItem" (the workflow will be bound to the relevant list after deployment!)
A GetDynamicValueProperties activity shall get the Content of a field "customer" of type "Person".
How to get what's in the field "customer" of the current list item?
Studying other docs there's advised to use LookupSPUser activity. Is this the right way and if so how to get the necessary ID (= id of the value in "customer")?
