(MyFaces) ExtensionsFilter not correctly configured

Front-end
#1

Bom dia turma,

Estou desenvolvendo um projeto utilizando JSF (MyFaces + Tomahawk) + Spring + Hibernate.

Estava funcionando tudo legal até que resolvi utilizar o Calendar (t:inputCalendar) e apareceu o seguinte erro:

ExtensionsFilter not correctly configured. Resource mapping missing. Resources cant be delivered. Please see: http://myfaces.apache.org/tomahawk/extensionsFilter.html

e o stack trace é:

java.lang.IllegalStateException: ExtensionsFilter not correctly configured. Resource mapping missing. Resources cant be delivered. Please see: http://myfaces.apache.org/tomahawk/extensionsFilter.html at org.apache.myfaces.renderkit.html.util.AddResourceFactory.throwExtensionsFilterMissing(AddResourceFactory.java:371) at org.apache.myfaces.renderkit.html.util.AddResourceFactory.checkEnvironment(AddResourceFactory.java:352) at org.apache.myfaces.renderkit.html.util.AddResourceFactory.getInstance(AddResourceFactory.java:288) at org.apache.myfaces.custom.calendar.HtmlCalendarRenderer.addScriptAndCSSResources(HtmlCalendarRenderer.java:297) at org.apache.myfaces.custom.calendar.HtmlCalendarRenderer.encodeEnd(HtmlCalendarRenderer.java:114) at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:536) at com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:242) at com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239) at com.sun.facelets.tag.jsf.ComponentSupport.encodeRecursive(ComponentSupport.java:239) at com.sun.facelets.FaceletViewHandler.renderView(FaceletViewHandler.java:580) at org.ajax4jsf.framework.ViewHandlerWrapper.renderView(ViewHandlerWrapper.java:101) at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:384)

Verifiquei o meu web.xml e está tudo correto, não sei mais o que configurar.
Segue em anexo o web.xml.

Desde já agradeço a ajuda.
