I have a view that is included in another view. I'm running into problems with f:metadata in the included view. Not sure how to go about it. I've updated both views and restarted the server. No luck.
Parent view
<ui:include src="sub_entityIndexPagination.xhtml">
<ui:param name="entityIndexBean" value="#{articleIndexBean}"/>
</ui:include>
Sub view
<ui:composition
xmlns="http://www.w3.org/1999/xhtml"
xmlns:c="http://java.sun.com/jsp/jstl/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
>
<f:metadata>
<f:viewParam name="pn" value="#{entityIndexBean.currentEntityPageNumber}" />
<f:event type="preRenderView" listener="#{entityIndexBean.toCurrentEntityPage()}" />
</f:metadata>
<c:forEach var="pageNumber" begin="1" end="${entityIndexBean.getEntityPageCount()}">
<h:outputLink value="ar_index.xhtml">
<h:outputText value="${pageNumber}" />
<f:param name="pn" value="${pageNumber}" />
</h:outputLink>
</c:forEach>

The <f:metadata> can't be declared in an include file. It has to be declared in the top view (the file which you indicated as "parent view"). It should be exactly that view which is directly referenced by the request URL.
That said, it's completely wrong to have a <html> in an include file. You're this way effectively nesting <html> tags which only results in syntactically invalid HTML. It would probably be worth the effort to take a JSF pause and learn some basic HTML first. JSF is ultimately just a HTML code generator.

Another reason this might show up is if there is any tag, including , between <ui:composition> and <f:metadata> in facelets.
e.g:
Good:
<ui:composition
...
template="...">
<f:metadata>
<f:viewParam ...
Also OK, in case you need to set params on f:view:
<ui:composition
...
template="...">
<f:view ...params goes here... /> <!-- ends here, does not enclose anything -->
<f:metadata>
<f:viewParam ...
Bad:
<ui:composition
...
template="...">
<f:view> <!-- you don't even need this with facelets unless you want to pass in parameters. -->
<f:metadata>
<f:viewParam ...
</f:view> <!--f:view encloses f:metadata so f:metadata is no longer a direct child of UIViewRoot. -->
