A modern programming language that makes developers happier.

kotlinlang

looks like a possible known issue with kotlin's `Unit`, or rather Data Bindings ability to deal with it.

Yeah I’m starting to get the impression that it’s not possible (currently). Thanks for the link, maybe i should file an issue

Afaik, the workaround for this is just to pass a function that returns anything other than Unit (so `function: (View) -&gt; Any`), not quite as clean but not a bad workaround

I'll be curious to see if that works for you.  I haven't done too much in data binding myself.

Yep, it’s working for me after changing the return to `Any`. I can still use `Unit`, which makes it even weirder

Example: ```    fun testFunction() = Unit
``` throws StackOverflowException, but ```    fun testFunction(): Any = Unit
``` works fine

As far as I can tell. Still need to test more
