Hi everyone,

Now im trying to use devhub for the first time and thing are not goin so well.

I'm using the Qlik Sense example

https://help.qlik.com/en-US/sense-developer/3.2/Subsystems/Extensions/Content/Widget/widgets-example...

but for some reason the functions not working.

app.doReload()

app.forward()

app.clearAll()

app.lockAll()

app.unlockAll()

For the example i've expected once that i select something in my pizza's bar and clicked on Reload or Clear function a deselection will happen, but nothing.

Any Help please?
