alloy:fieldField is a UIPanel component that renders a
<div>element and a
<label>element in order to wrap a field. Since it extends HtmlPanelGroup, it supports all the features of h:panelGroup.
General UsageA label can be specified via the label attribute. In addition, the id attribute is typically referenced by the f:ajax tag in order to re-render an input field and a corresponding message.
If a child input component like alloy:inputText fails validation, then the FacesMessage that is queued for the child input will use the label of the field. This provides the end-user with a better context as to which input field failed validation.
