Extending f:convertDateTime
Hi!
I use facelets and want to extend f:convertDateTime to understand the String "Now" and converts it to the current Date. All attributes of f:convertDateTime should be also supported.
I tried the following:
faces-config.xml
<converter>
<converter-id>ExtendedDateConverter</converter-id>
<converter-class>com.bla.util.ExtendedDateConverter</converter-class>
</converter>
ExtendedDateConverter.java
public Object getAsObject(final FacesContext context,final UIComponent component,final String value){
String dateValue = value;
if (NOW.equals(value)){
dateValue = getAsString(context, component,new Date());
}
return super.getAsObject(context, component, dateValue);
}
bla.taglib.xml
<facelet-taglib>
<namespace>bla</namespace>
<tag>
<tag-name>testConverter</tag-name>
<converter>
<converter-id>ExtendedDateConverter</converter-id>
</converter>
</tag>
</facelet-taglib>
So far so good. This works fine for attributes which require a String parameter like dateStyle, patter and so on.
<h:inputText value="#{EditProduct.product.activation}" size="25">
<bla:testConverter pattern="dd.MM.yyyy HH:mm:ss" />
</h:inputText>
Works fine, but if i try to add a timeZone which requires java.util.TimeZone i get an exception
<h:inputText id="activation2" value="#{EditProduct.product.activation}" size="25">
<bla:testConverter pattern="dd.MM.yyyy HH:mm:ss" timeZone="Europe/Vienna" />
</h:inputText>

While
<h:outputText value="#{EditProduct.product.activation}">
<f:convertDateTime pattern="dd.MM.yyyy HH:mm:ss" timeZone="Europe/Vienna" />
</h:outputText>
works just fine.
Seems like JSF can't convert a String to a timezone...but how does it work for f:convertDateTime?
Thanks for your help!!
Best wishes
