The first action you are creating is to load two pages with details from the main view. You want the action to act on each individual row. Inside the 'display_columns' element, add an additional 'col' element in 'action' type to display a trigger for each row. The trigger will then execute the action against its associated row.
The 'col' element attribute 'type' will have a value 'action' to indicate that this column is going to call an action. The attribute 'name' will be set to the same name as the action it is to call.
The action framework will be defined on this page. The element 'c_title' is set to the column title, and the element 'icon' is set to the file name of the icon to be displayed for the trigger.
