In March, I learned about the event of Scotiabank Calgary Marathon 2013. Soon I registered the event. That's why it takes me so long time to see the result.

For example, a table list controller, parent, may push to an item edit controller, child, when an item is selected. The easiest way to is to set a property in child controller and pass the reference to parent controller to child's property.

By using this tool, permissions can be added, deleted or modified as well. Based on this findings, I used PowserShell to create a script to get folder permissions. I am planning to further to enhance this script to create duplicated permissions for a specified folder.
