[Solved] Menu throws exception "Value cannot be null" after update to Q3 2011 SP1 (2011.3 1306)

[Telerik Admin]

Hello,

After updating to SP1 of Q3 2011 release (2011.3 1306) of Telerik Extensions for ASP.NET MVC, it is possible to get following error:

[ArgumentNullException: Value cannot be null.
Parameter name: value]
   System.Web.Caching.CacheEntry..ctor(String key, Object value, CacheDependency dependency, CacheItemRemovedCallback onRemovedHandler, DateTime utcAbsoluteExpiration, TimeSpan slidingExpiration, CacheItemPriority priority, Boolean isPublic) +8948527
   System.Web.Caching.CacheInternal.DoInsert(Boolean isPublic, String key, Object value, CacheDependency dependencies, DateTime utcAbsoluteExpiration, TimeSpan slidingExpiration, CacheItemPriority priority, CacheItemRemovedCallback onRemoveCallback, Boolean replace) +93
   System.Web.Caching.Cache.Insert(String key, Object value) +75
   Telerik.Web.Mvc.Infrastructure.Implementation.CacheProvider.Insert(String key, Object value) in f:\108\Griffin\Current Full\Sources\Source\Telerik.Web.Mvc\Infrastructure\Implementation\CacheProvider.cs:20

This issue will be fixed in the next official update and for the time being you could use the internal build that can be found here (2011.3.1310). 

Please accept our sincere apologies for the inconvenience.

Regards,
Telerik Admin
