Format PrimeFaces Slider InputText

I have a PrimeFaces slider with an associated inputText. Everything is working fine, except I can´t find a way of formatting the inputText value. I want the inputText to show and get values in currency format.

What I've tried so far:

Update: it was found later that the second option exception is thrown because f:convertNumber expects a number type bean property, not an integer one. Both solutions shown below work around this issue.

Is there a simple way of doing this without using jQuery?

Thanks!

So there are 2 ways of solving this problem:

  1. Creating a custom converter (drafted by @giaffa86 in his solution);
  2. Enabling Number getters and setters to the int property and using them with inputText (what's simpler, IMO).

The code below shows how to implement the second option.

TestView.java

@ManagedBean(name="testView")
@ViewScoped
public class TestView {

    private int realValue = 500;

    public int getValueAsInt() {
        return this.realValue;
    }

    public Number getValueAsNumber() {
        return (Number)realValue;
    }

    public void setValueAsInt(int value) {
        this.realValue = value;
    }

    public void setValueAsNumber(Number value) {
        this.realValue = value.intValue();
    }

    public void onSlideEnd(SlideEndEvent event) {
        this.realValue = event.getValue();
    }
}

view.xhtml

    <p:inputText id="input" value="#{testView.valueAsNumber}">
        <p:ajax update="slider" />
        <f:convertNumber currencySymbol="$" type="currency"
            integerOnly="true" />
    </p:inputText>

    <h:inputHidden id="hidden" value="#{testView.valueAsInt}" />
    <p:slider id="slider" for="hidden" minValue="0" maxValue="1000" step="10">
        <p:ajax event="slideEnd" listener="#{testView.onSlideEnd}" update="input" />                    
    </p:slider>

This solution, as the first option, also loses live update, but that's no problem in my scenario.

Below I posted minimal requirements to obtain a custom inputText but you lost live update on it.

SliderView.java

private int number1 = 0;
private String number2 = String.valueOf(number1);

public int getNumber1() {
return number1;
}

public void setNumber1(int number1) {
this.number1 = number1;
}



public String getNumber2() {
return number2;
}

public void setNumber2(String number2) {
this.number2 = number2;
}

public void converToInt() {
log.debug(number2);
//TODO should be improved
this.number1 = Integer.parseInt(number2);
}

public void onSlideEnd(SlideEndEvent event) {
log.debug("current number: " + event.getValue());
this.number1 = event.getValue();
this.number2 = String.valueOf(event.getValue());

}

slider.xhtml

<h:form id="bcr_form_2" styleClass="form">
    <h:panelGrid columns="1" style="margin-bottom: 10px">
        <p:inputMask id="output" value="#{sliderView.number2}">
            <p:ajax event="keyup" listener="#{sliderView.converToInt}" update="@form:txt @form:slider" />
            <f:converter converterId="CurrencyConverter" />
            <pe:keyFilter regEx="/[0-9_]/i" />
        </p:inputMask>
        <h:inputHidden id="txt" value="#{sliderView.number1}" />
        <p:slider id="slider" for="txt" style="width: 200px">
            <p:ajax event="slideEnd" listener="#{sliderView.onSlideEnd}" update="@form:output" />
        </p:slider>
    </h:panelGrid>
</h:form>

CurrencyConverter.java

@FacesConverter("CurrencyConverter")
public class CurrencyConverter implements Converter {
  @Override
  public Object getAsObject(FacesContext context, UIComponent component, String value) {
    return value.replace('€', ' ').trim();
  }

  @Override
  public String getAsString(FacesContext context, UIComponent component, Object value) {
    return value.toString() + "€";
  }
}

Glad to be helpful.
