'NotEqual' is not a valid value for property NoesisApp.DataTrigger.Comparison.
Hi. I am trying to change the visibility property of a view according to events.
I have this code in the xaml file. I use the Menu3D sample as a guide.
Why this error appears and how I can solve it?

<ei: ChangePropertyAction PropertyName = "Visibility" Value = "Hidden" />
</ ei: DataTrigger>

I assume you are including Interactivity source code in your game/app, or linking against NoesisApp.lib. And registering all the components from that package: viewtopic.php?f=3&t=1893#p10663 or viewtopic.php?f=3&t=1893&start=10#p10664
Anyway, I see you are setting Value property with "{x:Local Static:State.MainMenu}", that is not correct, it should be:
The markup extension is x:Static, then you specify the static type member with Local:State.MainMenu. "Local" prefix is replaced during xaml parse with the specified namespace to resolve the type name, in this case will be "YourNamespace.State". If that type is an enum, then "MainMenu" will be one of the values of the enum.
