Hi!

I’m trying to create a global error event handler that shows a modal with the error message, but I’m currently having difficulties when setting up the event.

Just below the `<App>` tag I have declared `<UserEvent ux:Name="globalErrorEvent" />` along with `<OnUserEvent EventName="globalErrorEvent" Handler="{handleGlobalErrorEvent}"/>`

Then somewhere dark and cozy I execute the handler `raiseGlobalErrorEvent : function(){ globalErrorEvent.raise() }` and get the following log output:

````auto
JS stack trace: ReferenceError: globalErrorEvent is not defined
    at raiseGlobalErrorEvent (Cards/InputCards/User.ux:189:49)
 in Fuse.Reactive.FunctionMirror<Cards/InputCards/User.ux:189>```

It currently works if I, instead of using javascript, use the markup like this
```<Clicked>
      <RaiseUserEvent EventName="globalErrorEvent" />
</Clicked>```

Any suggestions on how I can trigger this directly from javascript?

Hi Palton,

to achieve this you’ll need to use an approach that is shown in [this example](https://github.com/fusetools/fuse-samples/tree/master/Samples/UserEvents).
