Question

I work with JSF, RichCalendar and a4j. My problem: I want to rerender components of my website but if someone edits the date of one rich-calendar input field to ’12.aa.2012′ a FacesMessage is thrown, which is correct and good. Anyway my a4j-rerender-event did not get triggered due to unhandeld facesMessages. On my Tomcat-Console I get this errorMessage:

WARNUNG: There are some unhandled FacesMessages, this means not every FacesMessage had a chance to be rendered.
These unhandled FacesMessages are: 
- Bitte ein gültiges Datum eingeben!

How can I handle this problem, I tried several ways to show the errorMessage and I can figure out how to show it, but there is still the warning and still the not triggered-rerender-event?

Thanks in advance.

UPDATE: here is the code to my question. As you can see after you select one of the radio buttons, one dateContainer will show up, for example ‘admissionDateContainer’. If you change the value to ‘asd’, and select another choice, no rerendering of the related box happens, the choice will change but the wrong dateContainer will stay there ?!

<h:panelGroup layout="block" id="caseTypeContainer" rendered="#{CaseController.isFallContainer}" styleClass="fieldContainer">
    <t:outputLabel for="caseType" styleClass="generalInputLabel" style="width:200px; float:left;" value="#{resources.labels['caseType']}:" title="#{resources.labels['caseType']}" />

Answer 1

Add <rich:messages or <rich:message to your page

Take a look at rich:messages and rich:message

Also make sure that they are being rendered after your button is being clicked… add their ids or their wrapper (@form for example) ids to the reRender of your calendar
