I want to be able to give the user on a task form the ability to select multiple names from a checkbox list. The list is a predefined usernames that can be selected on the current task and who will also be assigned the next task. I don't want to add a people field and have default values as this will allow the users to insert names outside of the predefined list - which is not allowed.
I created a predefined choice field with names, then when I try to use those names in a next task to assign it to them, the workflow is unable to resolve the names and errors the workflow. I tried to create a people variable and insert user profiles based on account name, still doesn't resolve. I tried also to query user profiles based on the names, get the emails and save it in a collection variable then take that variable into the task, still didn't fix it.
Can someone give a hint of what am I missing?
I'm using SharePoint/Nintex 2010.
