show empty textfield for integer/double property

hi,

is there any way to remove or not to show the "0" or "0.0" for t:textfield
that bound to integer/double property? in my class file "MyPage.java", i
have 

public class MyPage{
    @Property
    @Persist
    private int theValue;
}

for MyPage.tml in t:form:

<input type="text" t:type="TextField" t:value="theValue"/>

it shows "0" because it is integer type in the textfield, what i wanted to
achieve is to not showing anything on the textfield at all. can this be
done?

please advice.

wesley

Try changing the type from int to Integer. As any other ordinary Java int  
field, it is automatically initialized with 0 when the instance is built.  
Null Integer values are shown as blank space in the TextField component.
