JSF input failed double conversion error

I have a JSF2 application that uses Spring 3.0. I have a bean that has a type property List<Double>with 5 elements:

public class MyBean {
    private List<Double> values; 
    public List<Double> getValues() {
        if (values == null) {
            values = new ArrayList<Double>(5);
                for (int i = 0; i < 5; i++) {
                    values.add(null);
                }
        }
        return values;
    }
    public void setValues(List<Double> values) {
        this.values = values;
    }
}

In my xhtml file, I have this for each element:

<h:inputText id="value1" value="#{myBean.values[0]}">
    <f:convertNumber pattern="#########0.##" />
</h:inputText>

My goal is to get values ​​like ArrayList. In addition, I do not want to maintain individual properties for each participant. A future requirement will cause the total number of values ​​to be dynamic (rather than hardcoded 5), so I can use a loop to determine the inputs for each element, but now we will not focus on that.
