Question: Can you point me to documentation for creating generic tables which list 'in vs out property direction' in respective table columns?

Background:

I want to create generic table in Cameo.

• The first column displays activities.
• The second column displays the properties designated as 'in'.
• The third column displays the properties designated as 'out'.

Approach so far:

• Created generic table
  
• Column 1 lists 'activities'
  
• Column 2 displays input/outputs using 'New Custom Column...' => Metachain Navigation​​​​​​​
  • Metachain Navigation​​​​ (MN)​​​​​​​​​​ Row 1: Under 'Metaclass or Stereotype' - selected 'Activity'
    
    • Under 'Property' - inserted 'Owned Parameter'
      
  • MN​​​​​​​​​​​​​​ Row 2: Under 'Metaclass or Stereotype' - selected 'Parameter'
    
    • Under 'Property' - inserted 'Name'
      
• Column 3 attempts to display property direction by doing the following 
  
  • MN​​​​​​​ Row 1: Under 'Metaclass or Stereotype' - selected 'Activity'
    • Under 'Property' - inserted 'Owned Parameter'
  • MN​​​​​​​​​​​​​​ Row 2: Under 'Metaclass or Stereotype' - selected 'Parameter'
    • Under 'Property' - inserted 'Direction' 

Selecting direction does not result in 'in' vs 'out' being displayed.

For troubleshooting I referenced: 

• Tables (nomagic.com)
  
• Selecting criteria (nomagic.com)
• Specification window (nomagic.com)

Thank you,

Scott
