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) -> 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
