Examples of com.sun.faces.el.ChainAwareVariableResolver

com.sun.faces.el.ChainAwareVariableResolver

This special VariableResolver serves as the "original" VariableResolver that is passed to the one-arg ctor for the first custom VariableResolver that is encountered during application configuration. Subsequent VariableResolver instances get passed the previous VariableResolver instance, per section 10.4.5 of the spec.

The "specialness" of this VariableResolver is found in its {@link #resolveVariable} method, which delegates to the head of the"correct" ELResolver chain based on the context in which this expression is being evaluated. If the expression being evaluated originated in a JSP page, the Application's ExpressionFactory is used to create a ValueExpression, which is then evaluated to resolve the variable. This will cause the ELResolver chain described in section 5.6.1 of the spec to be used. If the expression being evaluated originated in a programmatic API call, the Application's ELResolver is used to resolve the variable. This will cause the ELResolver chain described in section 5.6.2 of the spec to be used.
