title: Android Studio 2.2 Databinding error
body: <p>I've just updated Android Studio to <code>2.2</code>, Gradle plugin to <code>2.2.0</code> and I am getting the following error in the project when initializing views using <code>DataBinding</code>. It says <code>Type T has incompatible upper bounds</code>. Android Studio offers no suggestions on how to fix this. Casting the binding to the exact class doesn't solve the issue.</p>

  <p>It still compiles and runs though, but project is full of red errors - one for each <code>DataBinding</code> initialization. Any ideas?</p>
