Hum... Maybe I'm not very clear.
Here is my custom converter that i register in the
xwork-conversion.properties (by adding
java.util.Date=com.blabla.DateConverter) :
import ognl.DefaultTypeConverter;
public class DateConverter extends DefaultTypeConverter
{
//~ Methods
////////////////////////////////////////////////////////////////
public Object convertValue(
Map context,
Object o,
Member member,
String s,
Object value,
Class toType)
{
if( value == null )
return null;
Object result = null;
if (toType == String.class)
{
if (value instanceof Date)
{
Date sa = (Date) value;
SimpleDateFormat sdf = new
SimpleDateFormat("dd/MM/yyyy");
result = sdf.format(sa);
}
}
else if (toType == Date.class)
{
if (value instanceof String || value instanceof String[])
{
String sa;
if(value instanceof String[] )
sa = ((String[]) value)[0];
else
sa = (String) value;
SimpleDateFormat sdf = new
SimpleDateFormat("dd/MM/yyyy");
try
{
result = sdf.parse(sa);
}
catch (ParseException e)
{
result=null;
}
}
}
else
throw new UnsupportedOperationException("Conversion d'une date
en
"+toType.getName()+" n'est pas implementee.");
return result;
}
}
"Ahh... Good question... I guess you don't want to see 2 messages? 2"
"messages might be ok:"
"Your text "Foo Bar" could not be parsed as a date"
"You must enter a date for birthday"
My question : how can i do to see the message "Your text "Foo Bar" could not
be parsed as a date", what can i do in my dateconverter to add a FieldError
????
Cheers.
Richard.
