If you are creating a custom converter in wicket 2.0, you just implement the IConverter interface, use the converter in your formcomponent, etc.
When the form is submitted the wicket.markup.html.form.FormComponent#convert() method will be called. If you configurated your custom converter the right way, the convertToObject() method on your custom converter will be called. In this method you should throw a ConversionException if the converter cannot convert the input to the specified type. When this exception is thrown it will be caught in the wicket.markup.html.form.FormComponent#convert() method, a validation error is created with message key 'TypeValidator' or 'TypeValidator.classname'. I would like to have the possibility to assign to custom message key to that validation error. Because there are situations that you have different converters which converts a String to (for example) a Double with different error messages. -- View this message in context: http://www.nabble.com/Custom-converter-and-custom-error-message-wicket-2.0-tf2813302.html#a7850871 Sent from the Wicket - Dev mailing list archive at Nabble.com.
