Custom converter and custom error message wicket 2.0
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.

I just did this.
So if you get a fresh copy from svn you should have the code.

Yes, you are right, it is used as well in the convert method. May be we need
to wait when they synchronize the 1.x and 2.0 code.

yeah we should add support that you can throw an ConversionException with
the preferred key already set in it.
can you add a feature request for this in jira?
