Query Deactivated User

Hi, 

Could you please help me creating an interface where I can query for deactivated users. The interface is to start a process to reactivate the user. So far I have tried two methods unsuccessful:

1. User picker field only returns active users. 

2. Record picker field on RecordType 'User' does return all users in the search field, but when I select one I get a uuid as a result. I haven't found a solution to return this uuid back into a User type. Please find my code here below. 

a!localVariables(
  local!user,
  a!formLayout(
    label: "Heractiveer account",
    contents: {
      a!pickerFieldRecords(
        label: "Record Picker",
        labelPosition: "ABOVE",
        recordType: 'recordType!{SYSTEM_RECORD_TYPE_USER}User',
        value: local!user,
        saveInto: local!user,
        validations: {}
      )
    },
    buttons: a!buttonLayout(
      primaryButtons: {
        a!buttonWidget(
          label: "Heractiveer",
          icon: "check-circle",
          submit: true,
          style: "PRIMARY",
          loadingIndicator: true
        )
      },
      secondaryButtons: {
        a!buttonWidget(
          label: "Terug",
          value: true,
          saveInto: ri!cancel,
          submit: true,
          style: "NORMAL",
          validate: false
        )
      }
    )
  )
)

Do you know a solution for either returning a user instead of a uuid, of a method to convert an uuid to a user?

Thanks for your help in advance, 

Jesper
