We have been using RadGridView for over a year, quite successfully. We had an old project that implemented the Persistence Framework (using PersistenceManager) and successfully saved/loaded layouts. Now, however, in a new project using the latest DLLs (2013.2.724) the save works fine (supposedly) but the load fails. The error message in the output window is "A first chance exception of type 'System.NullReferenceException' occurred in Telerik.Windows.PersistenceFramework.dll".
We compared streams after saving and after loading and they are identical - so insofar as the save is working correctly, it is persisting the layout to the stream and then loading it back.
We have downloaded samples from these forums and they do indeed work (in the sample) so no one is sure what is going on. The grid we're trying to save is fairly trivial, nothing special. No custom properties, no custom filters. In fact, we copied the Proxies.cs and RadGridViewCustomPropertyProvider.cs from the sample application and it still fails with the same error.
Any assistance would be greatly appreciated. Opened a support ticket on this as well, but have not heard back yet.
