After upgrading to Fuse 1.3.0 the sender argument is not valid anymore:

```
<App>
    <DockPanel >

        <JavaScript>
            function test(args) {
                console.log(JSON.stringify(args));
                console.log(args.sender);
            }

            module.exports = {
                test: test
            };
        </JavaScript>
        <Panel Dock="Top" ux:Name="mnuHome">
            <Grid Margin="0,50,0,0" Rows="auto,auto">
                <Rectangle Row="0" Color="#232323" Width="200" Height="200"/>
                <Text Row="1" Value="Test" TextAlignment="Center" Margin="0,10,0,0"/>
            </Grid>
            <Clicked>
                <Callback Handler="{test}" />
            </Clicked>
        </Panel>
        

    </DockPanel>
</App>

```

It’s null now.

I’ve reproduced this issue, and it’s indeed a regression in 1.3. Thanks for the report.

OK, I think I’ve figured out the issue, and I’ve [sent a PR](https://github.com/fusetools/fuselibs-public/pull/660) to fix it. If you’re daring, you could try building from source yourself until this has made it into a release.

This should now be fixed in Fuse 1.3.2
