Is this a general databinding issue or question? You are more likely to get a response from somewhere like StackOverflow.
Please be as detailed as possible and include a (formatted) stacktrace if relevant. A sample project that reproduce the problem goes a long way!
Please give an example use-case on why the feature is useful. Keep in mind the scope of this project is to bind data to RecyclerView/ListView/ViewPager etc, not to add additional features to those views.
