Custom coercion from String to Long

[Radek Terber]

Hi all

I need the cutom coercion from String to Long, which will translate empty
strings to null Long value. I tried add contribution to my AppModule, but
with no success - coercion to Long is still processed by old manner. Is
there any way to do it?

Thans.


Here is part of my AppModule:
============================
     public static void contributeTypeCoercer(Configuration<CoercionTuple>
configuration) {

    Coercion<String, Long> cc = new Coercion<String, Long>() {
            public Long coerce(String input)
            {
             if(input == null || input.length() == 0) {
             return null;
             }
                return new Long(input);
            }
        };

        CoercionTuple<String, Long> tuple = new CoercionTuple<String,
Long>(String.class, Long.class, cc);
        configuration.add(tuple);

    }
