obtain the component value


Hi,

I want to implement a validator. All works fine, the only problem I have is
the fact that I need the value of another component (radio button). How can
I obtain the other value?

the code is this:
public void validateInputValue(FacesContext context, 
            UIComponent toValidate,
            Object value) {
		BigDecimal inputValue = (BigDecimal) value;
		if (inputValue .compareTo(BigDecimal("1000")) > 0) {
			((UIInput)toValidate).setValid(false);
			
			FacesMessage message = new FacesMessage("error");
			context.addMessage(toValidate.getClientId(context), message);
		}		
	}

validator="#{enterprise.validateInputValue}"

The other component is:
<h:selectOneRadio id="radioValue"
	value="#{enterpirse.radioValue}">
        <f:selectItem itemValue="true" itemLabel="kWh" />
	<f:selectItem itemValue="false" itemLabel="MWh" />
</h:selectOneRadio>

In the method "validateInputValue" from the backing bean I want to know also
the boolean value radioValue.

Hi,

I suggest to look on children of parent component:

toValidate.getParent().getChildren();
//and find amoint the children needed value - for example by  -
if(uiComponent.getId().equals("radioValue")){
 //and cast the Radibutton component to related JSF class - I dont remember
the RadioButton class.
 ((HtmlRadioButton)uiComponent).getValue();
}
