Primefaces datalist + PrettyFaces

How can i use PrettyFaces in a dataList item link ?

<p:dataList value="#{mybean.cities}" var="city">
  <h:link outcome="pretty:goCity">
      TEXT
      <f:param name="city" value="#{city.city}" />
      <f:param name="cityId" value="#{city.id}" />
  </h:link>
</p:dataList>

And this is my pretty-config:

<url-mapping id="goCity">
    <pattern value="/#{cityId:city.id}/#{city:city.city}" />
    <view-id value="/page.xhtml" />
</url-mapping>

I got this error:

Your setup looks absolutely correct. It seems like <p:dataList> doesn't work exactly like <h:dataTable> or <ui:repeat> here.

You could try to replace the component with something like this:

<ul>
  <ui:repeat var="city" value="#{mybean.cities}">
    <li>
      <h:link outcome="pretty:goCity">
        TEXT
        <f:param name="city" value="#{city.city}" />
        <f:param name="cityId" value="#{city.id}" />
      </h:link>
    </li>
  </ui:repeat>
</ul>

Or with <pretty:link> instead of <h:link>:

<ul>
  <ui:repeat var="city" value="#{mybean.cities}">
    <li>
      <pretty:link mappingId="goCity">
        TEXT
        <f:param name="city" value="#{city.city}" />
        <f:param name="cityId" value="#{city.id}" />
      </pretty:link>
    </li>
  </ui:repeat>
</ul>
