Class AutoLabelResolver

  extended by org.apache.wicket.markup.html.form.AutoLabelResolver
All Implemented Interfaces:, IClusterable, IComponentResolver

public class AutoLabelResolver
extends java.lang.Object
implements IComponentResolver

Resolver that implements the wicket:for attribute functionality. The attribute makes it easy to set up <label> tags for form components by providing the following features without having to add any additional components in code:

The value of the wicket:for attribute can either contain an id of the form component or a path to it using the standard : path separator. Note that .. can be used as part of the path to construct a reference to the parent container, eg ..:..:foo:bar. First the value of the attribute will be treated as a path and the <label> tag's closest parent container will be queried for the form component. If the form component cannot be resolved the value of the wicket:for attribute will be treated as an id and all containers will be searched from the closest parent to the page.
