title: Butterknife Required view with ID for field was not found in every fragment
body: <p>When I try to bind my views with Butterknife I get this <code>IllegalStateException</code> after every time I call <code>ButterKnife.bind(this, fragmentView!!)</code> method.</p>
  
  <p>For example:</p>
  
  <pre><code>//...BindView section
  @BindView(R.id.logoutButton)
  lateinit var logoutButton: View
  
  @BindView(R.id.closeSession)
  lateinit var closeSessionButton: View
  
  @BindView(R.id.settings)
  lateinit var settingsButton: View
  </code></pre>
  
  <p>And I get this:</p>
  
  <blockquote>
    <p>java.lang.IllegalStateException: 
        Required view login with ID 2131362018 for field logoutButton was not found. 
        If this view is optional add @Nullable (fields) or @Optional (methods) annotation.</p>
  </blockquote>
  
  <p>The point is that I DIDN'T BIND the 'login' view as the exception says.
  I bounded 'logutButton'.
  I did have 'login' view, but in the other fragment which has no connection to fragment where the exception appears.</p>
  
  <p>And this happening in every fragment, activity, or adapter or something else which needs binding views with butterknife.
   And every time Butterknife tries to bind, an absolutely random view for the field that comes first in declaration order (only first <code>@BindView</code> annotation affected, the next annotation are fine)</p>
  
  <p>I'm using <code>@Nullable</code> annotation and it's helping perfectly (even after I deleted <code>@Nullable</code> annotation - fragment works fine). But I have lots of fragments and activities, so I can't check all of them and add the <code>@Nullable</code> annotation.</p>
  
  <p><strong>How I can find the source of this problem so that it never happens again?</strong></p>
