Specifying an Additional Super Class
When the wizard creates a CSP Page class, it bases it on %CSP.PageOpens in a new tab, which is the super class for all CSP pages. We can see this in the Studio Inspector.
We also want this class to inherit from our Cinema.UtilsOpens in a new tab class, so that it can make use of methods defined there.
We do this by clicking the ... button to display the Super Class dialog and add the Cinema.UtilsOpens in a new tab class to the list of super classes.
