JumpList ObjectDisposedException

[Alexander]

I am trying to open a phoneapplicationpage xaml file that only contains a RadJumpList in Blend, but receive errors...

ObjectDisposedException: Cannot access a disposed object.
Object name: 'NativeObject'.
StackTrace
   at System.Windows.DependencyObject.MS.Internal.IManagedPeerBase.get_NativeObject()
   at MS.Internal.XcpImports.DependencyObject_SetParentForInheritanceContextOnly(DependencyObject doh, DependencyObject parentDO)
   at System.Windows.DependencyObject.UpdateEffectiveValue(DependencyProperty property, EffectiveValueEntry oldEntry, EffectiveValueEntry& newEntry, ValueOperation operation)
   at System.Windows.DependencyObject.InvalidateProperty(DependencyProperty property)
   at MS.Internal.FrameworkCallbacks.InvalidateProperty(IntPtr nativeTarget, UInt32 propertyId)

The XAML is this:

<telerikDataControls:RadJumpList x:Name="radJumpList" />
</Grid>
</Grid>
</phone:PhoneApplicationPage>

What do I have to do to fix this?

Hello Alexander,

We have addressed a similar issue and have released an Internal Build containing the fix. Can you please try downloading the lastest IB available through your Telerik account and replacing your installation assemblies with the ones in the IB to see how it works for you?

Thanks for your time.
