@TotallyInformation: It indeed works fine, as long as I keep the code in the template node. But as soon as I use it in my own UI contribution, nothing ... But thanks for spending your time on this one!

@nisiyama: If have tried your new version of beforeEmit, and that seems to do the job!

Did a simple test by injecting msg.payload = "_Hello world_" or "_Hello mars_" into my UI node like this:

When I use now the following code snippet:

```auto
initController: function($scope, events) {
    $scope.$watch('msg', function(newVal, oldVal) {
        console.log('Watch is called ...');
        console.dir(newVal);
        console.dir(oldVal);
        console.dir($scope.msg);
    })
}

```

Then the stuff below is being logged in my Chrome console:

1. When dashboard is loaded in new tabpage, all 3 variables are undefined.
2. When a message (with msg.payload = "Hello world") is injected, the newVal contains the new message and the oldVal is undefined.
3. When a message (with msg.payload = "Hello mars") is injected, the newVal contains the new message and the oldVal contains the old message.
4. When the page is refreshed, newValue contains the **last message** and oldValue is undefined.

So $scope.msg is always equal to newVal (as expected), so we don't need the $scope.msg here anymore.  
And the on-load situation **(1)** can be ignored with a simple IF statement:

```auto
initController: function($scope, events) {
    $scope.$watch('msg', function(newVal, oldVal) {
        if (!newVal) {
            return;
        }

        console.dir(newVal);
    })
}

```

_But I hadn't expected that the refresh situation **(4)** would trigger the watch with an **older** message. Or is that normal behaviour to start again where we left before the refresh?_

It would be useful for other users to add your information to the above wiki page, and perhaps integrate it somehow in the 'reference' ui-list example node ...

Thank you very much!!!  
Bart
