How JSF el expression works and when a JSF variable resolver will be involved while evaluating any JSF exprestion?

Question

I am in a bit confusion.

That\'s how a JSF EL will work and how variable resolver involved while evaluating expressions like.

Answer 1

JSF uses Unified EL for evaluating expressions. The specification uses ELResolvers to determine the value of variables referenced in the expression.

The 'text' variable is likely getting stored in a standard scope (page, request, session, or application). The ScopedAttributeELResolver handles looking up objects from these scopes. The object returned by the ELResolver for 'text' variable is then used as the base for resolving the 'value' property.

There is a ResourceBundleELResolver that knows how to access objects contained within a ResourceBundle. The ResourceBundleELResolver will handle the looking up the 'value' property of the 'test' variable.
