Hello,
i migrated my webapp to jsf 1.2 and encountered an problem with the setting
of my backing bean properties.
When i submit a form with no values entered, the backing bean properties
(Double, Long, Number) are filled with 0.0 instead of null.
I found the following lines of code in the class
org.apache.el.lang.ELSupport:
private final static Long ZERO = new Long(0L);
public final static Number coerceToNumber(final Object obj) {
if (obj == null) {
return ZERO;
} else if (obj instanceof Number) {
return (Number) obj;
} else {
String str = coerceToString(obj);
if (isStringFloat(str)) {
return toFloat(str);
} else {
return toNumber(str);
}
}
}
Why the return ZERO ? On the jspx i see the 0.0 in the input fields. When i
now submit the site the 0.0 values are saved in my database. But the values
should be set to null.
Are there any workarounds for this problem.
Thanks for the help
Alex
