Can someone explain why kotlin compiler (or ide?) differentiates between these types of bugs? This was a problem for us

[Stephan Schroeder]

no idea, why there are different (or lack of) warnings. But in case you're not sure what the problem is in the first place:
::onEntityReady returns the method, but doesn't invoke it. it works for onError = ::postErrorEvent because there it takes the place of the lambda. Once you put it inside curly braces (a lambda funtion), you have to actually invoke it, in this case onError = {postErrorEvent(it)} (with it being the default name of the single parameter expected by the function assigned to onError)

@Stephan Schroeder thanks for reply. We already figured that syntax for method reference with ::

The "onError" is not a problem at all, the question is specifically about warning that IDE shows, which I assume developers didn't account for.

What is the actual warning on ::onEntityReady?
