Re: obtain the component value

[Anton Gavazuk <an...@gmail.com>]

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();
}
