Avoid the default value of 0 to display in h: inputText

Question

I have <h:inputText>one that takes a value longsimilar to this

<h:inputText value="#{ServiceTable.ID}" />

A property is declared as follows

public class ServiceTable {

    private long ID;

    // Getter and setter for ID.
}

When I open the page, I always see 0in the text box. How can i avoid this? I just need an empty text box. I am using JSF 1.2.

-Dorg.apache.el.parser.COERCE_TO_ZERO=false
