Managed bean property value not set to null
- by Vladimir
Hi!
I'm new to JSF, so this question might be strange. I have an inputText component's value bound to managed bean's property of type Float. I need to set property to null when inputText field is empty, not to 0 value. It's not done by default, so I added converter with the following method implemented:
public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException {
if (StringUtils.isEmpty(arg2)) {
return null;
}
float result = Float.parseFloat(arg2);
if (result == 0) {
return null;
}
return result;
}
I registered converter, and assigned it to inputText component. I logged arg2 argument, and also logged return value from getAsObject method. By my log I can see that it returns null value. But, I also log setter property on backing bean and argument is 0 value, not null as expected. To be more precise, it is setter property is called twice, once with null argument, second time with 0 value argument.
It still sets backing bean value to 0. How can I set value to null?
Thanks in advance.
