Empty value when 0 in primefaces inputtext component

Question

I have this primefaces inputText component that links to a double value in my backing bean:

<p:inputText id="valueI"
    value="#{productMB.total}">
    <f:convertNumber type="number" maxFractionDigits="0" />
</p:inputText>

When the total is 0 the inputText shows a zero. I need to show an empty value because a zero is visually ugly

How can I do that?

Use Double instead of double so that it defaults to null instead of 0.0. Primitives can't be represented as null (and therefore also not render as empty).

Do you know why this doesn't work on Integer values? – John Alexander Betts Sep 20 '13 at 16:56

It should also work for integers. Or are you observing this only after submitting a form? If so, then head to this duplicate: http://stackoverflow.com/questions/7206401/jsf-2-hiding-default-values-on-extends-number/7206474#7206474 – BalusC Sep 20 '13 at 18:01
Yes, you are right is only after submitting the form – John Alexander Betts Sep 21 '13 at 13:15
