All,
There have been a couple of questions about custom conversion lately.
I've looked into it a bit, and came to the conclusion that we should
re-evaluate how our conversion works for Wicket 1.3
(https://sourceforge.net/tracker/?func=detail&atid=684975&aid=1453022&group_id=119783).
For now, I added some convenience converters, specifically for use
when you want to provide a custom converter for a single component.
This is from the FormInput example of wicket-examples, and hopefully
illustrates it's use. BEFORE YOU USE IT THOSE CONVERTERS, DO READ
THEIR JAVADOCS PLEASE.
// TextField using a custom converter.
add(new TextField("urlProperty", URL.class)
{
public IConverter getConverter()
{
return new SimpleConverterAdapter()
{
public String toString(Object
value)
{
return value != null ?
value.toString() : null;
}
public Object toObject(String
value)
{
try
{
return new
URL(value.toString());
}
catch
(MalformedURLException e)
{
throw new
ConversionException("'" + value + "' is not a valid URL");
}
}
};
}
});
// TextField using a mask converter
add(new TextField("phoneNumberUS", UsPhoneNumber.class)
{
public IConverter getConverter()
{
// US telephone number mask
return new MaskConverter("(###)
###-####", UsPhoneNumber.class);
}
});
I hope this will make things a bit easier for those people that were
struggeling with custom conversion,
Eelco
