In order to restore a layout you must have registered all of the required panes with the layout system before restoring it. If you are just setting the layout using the declarative API then all of the same components will be registered. <br/ >If you have added any elements using FoundationLayout.registerItem() then you must ensure all of the same items have been added again. To make tracking what items are registered easier it is recommended in this case you explicitly name your registrations using the id parameter available on the RegisteredElementConfig and foundation-layout-item APIs.
You can use FoundationLayout.layoutRequiredRegistrations() to check which items are registered in a current layout in order to dynamically add any missing items before you can restore the layout
