I've got a problem considering updating my backing-bean within an ajax-roundtrip in a JSF2 application if the value is bound to a html5 input type=email.

  1. First of all, I created an "Html5InputRenderer", so that the JSF-runtime can create the html5-markup for a , in order to write

  2. The central "magic" the "Html5InputRenderer does is:

    markup.replaceAll("type=\"text\"", "type=\"email\"");

    within the overridden method encodeEnd(..) of javax.faces.renderer.Renderer.

  3. This h:input is put in to a form and enriched with f:ajax:

    <h:form id="form">                      
  <f:ajax render="testOut">
    <h:inputText id="test" renderedType="email" value="#{testBean.value}" />
  </f:ajax>
  <h:outputText id="testOut" value="#{testBean.value}" />
</h:form>

  4. The atribute 'renderedType' is the hint for the JSF-"Html5InputRenderer" to render the html5 markup for the h:input

  5. Test the snippet. It will not update #{testBean.value} although an ajax roundtrip is invoked by the JSF-runtime.

  6. Test the snippet removing the attribute 'renderedType', everything works like expected.

  • - well, a first clue is, that when the html output is according to the html5 spec, you cannot see the entered string in the POST values, that is a pity (seen via the FireBug network module). Modified in that way, the Jsf-runtime (I assume the javascript part) does not recognize that Html5-input and won't let the entered string participate in the outgoing ajax-request :( – Jens Kreidler Jun 12 '12 at 09:47
