I am quite happy with you current proposition. It seem to be flexible
enough to allow compound converters, while also being simple enough to
make your own converter. And there is only one interface, which is IMHO
a lot better and a lot less confusing than current IConverter and
ITypeConverter stuff.

that is not a problem. just add youre String.class converter to the
"compound" session Converter
Or override getConverter() and return yours.
you now know what is outgoing and incomming with that interface so that
shouldn't be a problem
But when the trunk is ready for 2.0 code. Lets test it out and evolve.

Johan,
It would be nice to have an ability to convert from string to string
for fields like phone numbers, zip codes, ssn, etc.

Hi,
first currently we have IConverter and ITypeConverter , i want
to combine those 2 to be one interface
And then a converter must be easy to make but also to understand.
So i can do this:
IConverter.convertToObject (String, Class)
IConverter.convertToString(Object)
Then writing a DateConverter is pretty simple, you have one
SimpleDateFormat (or more per locale)
and then in toObject you do parse and in toString you do format
The thing is we loose a bit of the more "generic" nature we have now
because in the current setup we could do:
conveter.convert(new Double(10), Integer.class) to convert from
a double to a integer.
Do we need this? We could make:
IConverter.convertObject(Object, Class) instead of
IConverter.convertToObject(String, Class)
besides to convertToString.
But that would complicate converters again.
That Class param can be ignored by a Converter impl (or it could
check if it was the type for which this converter is build.)
But having that class param there then it is possible to make a
compound converter and only have one interface
so that you can much easier make youre converter for a specific
textfield.
