StateListDrawable doesn't work

[ilyamuromets]

My test app have one view.
PixateFreestyle.setStyleClass(testView, "test_view");

In default.css:
.test_view { background-color: #ff0000; }

It works fine. But when I define the following I see that default state is trasparent drawable and pressed state is green drawable. Where my default red drawable?

.test_view { background-color: #ff0000; }
.test_view:pressed { background-color: #00ff00; }

This applies to View, ViewGroup.
