Custom Formatter<String> not working...

[johanr]

Hi,

I am trying to apply a Spring 3 custom Formatter in SWF 2.1.1:

class AccountNumberFormatter implements Formatter<String> {

	MaskFormatter mask;
	
	public AccountNumberFormatter(String pattern) {
		try{
			mask = new MaskFormatter(pattern);
			mask.setValueContainsLiteralCharacters(false);
		}catch(ParseException e) {
			// TODO
			e.printStackTrace();
		}
	}
			
	public String print(String object, Locale locale) {
		try{
			return mask.valueToString(object);
		}catch(ParseException e){
			return null;
		}
	}

	public String parse(String text, Locale locale) throws ParseException {
		return (String)mask.stringToValue(text);
	}
	
}

It is used through a custom annotation:

@AccountNumberFormat
private String accountNumber;

While other formatters work fine, this one does not. However in plain Spring 3 MVC, it works as expected.

When I have a look at SFW code, I see the following in class BindingModel:

	private Object getFormattedValue(String field) {
		Expression fieldExpression = parseFieldExpression(field, true);
		Class valueType = fieldExpression.getValueType(boundObject);
		if (isCustomConverterConfigured(field) || avoidConversion(valueType)) {
			fieldExpression = parseFieldExpression(fieldExpression.getExpressionString(), false);
		}
		Object value = fieldExpression.getValue(boundObject);
		if ((value instanceof String) == false) {
			if (avoidConversion(valueType) == false) {
				PropertyEditor editor = findSpringConvertingPropertyEditor(field, valueType);
				if (editor != null) {
					editor.setValue(value);
					value = editor.getAsText();
				}
			}
		}
		return value;
	}

If I override the class and remove the test on the String class, everything works fine.
So what is the reason behind this test ?
I had a look at the previous post but it did not help...

Any solution to this problem?

Any solution to this problem?

How can I use annotation based formatter in spring web flow without specifying strictly in flow code?

I finally got it working. Read here:
