IConverter.convertToObject not called
I've added an IConverter to a TextField<String>, to do formatting.
The converter's convertToString method is called on render, but
convertToObject is not called on form submit.
Some of the Wicket 1.3 examples suggest that this is a known problem,
and suggest using a wrapper type as a work-around.
As my experience suggests, is this stil teh problem in 1.4.x?
Thanks.

I see your point -- because you're right, it's not a /type/ conversion
I'm looking for.
But I am looking for a /format/ conversion. It would be handy if
IConverter allowed that too, by unconditionally applying the conversion.
The Wicket example of formatting phone numbers
(http://www.wicket-library.com/wicket-examples/forminput) demonstrates
this use case, and complains about the need for a work-around:
/**
* Represents a US phone number. We use this instead of the direct
string to trigger conversion to
* and from string. Conversion in general may be re-evaluated in Wicket
1.3, hopefully making this a
* hack from the past by then.

Is there by now a better work-around?
Or even handier, if say, a Google Guava Function or Apache Collections
Transformer could be added to components to do arbitrary conversions.
(Guava's T Function<F,T>.apply(F) takes an F and returns a T; Apache
Collections is similar, but without generics. Either library allows
Functions/Transformers to be arbitrarily composed (or "chained").

this is not a problem. yoru textfield's input is already a string, so
there is no need to convert it to a string. String
convertToObject(String) doesnt make sense.
