All Implemented Interfaces:

javax.faces.view.facelets.FaceletHandler

public class SetTagHandler
extends AliasTagHandler

Tag handler that exposes a variable to the variable map. Behaviour is close to the c:set tag handler except:

• It allows caching a variable using cache parameter: variable will be resolved the first time is is called and will be put in the context after
• The resolved variable is removed from context when tag is closed to avoid filling the context with it
• Since 5.4, variables are made available in the request context after the JSF component tree build thanks to a backing component.

Since:

5.3.1
