Steps to reproduce:

1. Deploy the jsf-showcase-webapp and navigate to the `h:button` General example.
2. Right-click and View Source

If the bug still exists `<script type="text/javascript"></script>` will appear before the closing body tag.

*Note:* [PartialResponseWriterImpl handles the ajax case correctly by checking if scripts.isEmpty() before attempting to render the scripts](https://github.com/liferay/liferay-faces-util/blob/master/util/src/main/java/com/liferay/faces/util/context/internal/PartialViewContextImpl.java#L97).{markdown}
