Hi, I have a method with the signature below:
fun function(paramFunction: (() -> Entity)?)

I am trying to pass the specified paramFunction as null through databinding:
android:onClick="@{() -> viewModel.function(null)}"

But I got an exception during compilation:

[kapt] An exception occurred: android.databinding.tool.util.LoggedErrorException: Found data binding errors.
****/ data binding error ****msg:cannot find method function(java.lang.Object) in class…

Does anyone have an idea how I can resolve this please?

I always had trouble with kotlin lambdas & databinding. I use regular interfaces instead.

Maybe with the paramFunction as optional parameter and @JvmOverload annotation
