Style file and Manifest. about android-unused-resources HOT 1 OPEN

Hi, I've found another error:

It seems that when styles extends from a parent style, it doesn't work. This is 
my new error:

<style name="MyButton">
  <!-- whatever -->
</style>

<style name="MyButton.Ok">
  <item name="android:background">@drawable/mybutton_ok</item>
</style>

And later, used as common in a layout:

<Button 
  android:id="@+id/btn_ok" 
  style="@style/MyButton.Ok"
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content"
  android:layout_gravity="center_vertical"
  android:text="@string/label_ok">
</Button>

And the exit from the script:
style     : MyButton_Ok

On the other bug (with the Manifest), the style extended from Theme.NoTitleBar 
and it was detected by the script as "unused". I think that both bugs are 
similar in that way.

Hope, again, this information is useful.
Miguel.
