javax.faces.application.Application.createValueBinding()

Call {@link #getExpressionFactory} then call {@link ExpressionFactory#createValueExpression}, passing the argument ref, Object.class for the expectedType, and null, for the fnMapper.
@param ref Value binding expression for which to return a{@link ValueBinding} instance @throws NullPointerException if refis null @throws ReferenceSyntaxException if the specified refhas invalid syntax @deprecated This has been replaced by calling {@link #getExpressionFactory} then {@link ExpressionFactory#createValueExpression}.
