Firstly, I found that if the app is opened in Portrait mode, the detail view is instantiated, but the Master is not.
I solved that by checking whether it is nil when the Detail opens:
try self.ParentSplitView.master = new MasterScreen catch end try
If the Master is dragged open from the left, I would like one of my detail screens to slide over to the right at the same time so that some data can be accessed.
Is that possible, or is the Detail always ‘disabled’ while the Master is visible?
