Timo -
Thanks for your response.
I did use a PatternValidator alone in my first approach, but while I
could verify that '123-45-6789' was a legitimate SSN, what I wanted to
additionally do was fill in my model object's string with '123456789'.
Now, if the setSsn() in the model object needs to incorporate this
behavior, I can live with that, but I thought it would be cleaner to
convert to/from the model using a custom converter.
Here is the full text (sans imports) of the SsnTextField:
public class SsnTextField<T> extends TextField<T>
{
static Pattern pattern = Pattern.compile("(\\d{3})[ \\-]*(\\d{2})[
\\-]*(\\d{4})");
public SsnTextField(String id)
{
this(id, null);
}
public SsnTextField(String id, IModel<T> object)
{
super(id, object);
add(new PatternValidator(pattern));
}
@Override
public final IConverter<String> getConverter(Class type)
{
return new IConverter<String>()
{
public String convertToObject(String value, Locale
locale)
{
String result = "";
result = value.substring(0, 3) + "-" +
value.substring(3, 5) + "-"
+ value.substring(5, 8);
return result;
}
public String convertToString(String value, Locale
locale)
{
String result = "";
Matcher fit = pattern.matcher(value);
if(fit.find())
for(int index = 1; index <= fit.groupCount(); index++)
result += fit.group(index);
return result;
}
};
}
}
