My first custom converter: why's not called?

问题:

I wrote my first JSF (1.2) custom converter. I declared it in faces-config.xml (converter-id and converter-class), wrote the Java class implementing getAsObject and getAsString methods. Then i put the converter in a page like this:

    <ice:selectInputDate id="ctldatanascita" 
                  value="#{beanrichiestaabilitazione.datanascita}"
          renderAsPopup="true">
      <f:converter converterId="cisConverterDate" />
    </ice:selectInputDate>

The class is istantiated, but the Converter interface methods are never called. What I'm missing?

回答1:

I don't do IceFaces, so I can't tell from top of head if that is normal. But Googling on "ice:selectinputdate converter" leads me to this topic as first hit: http://www.icefaces.org/JForum/posts/list/6163.page which confirms the behaviour you're seeing.

It als mentions several prerequirements and solutions:

• You need at least ICEfaces 1.7 DR2 or ICEfaces 1.6.2.
• Your converter needs to extend javax.faces.convert.DateTimeConverter.
• Or just use standard <f:convertDateTime> instead.
