问题 Please take a look at this below line of code in JSF <h:inputText id="name" value="#{customer.name}" /> Quote from java.sun.com: For an initial request of the page containing this tag, the JavaServer Faces implementation evaluates the #{customer.name} expression during the render response phase of the lifecycle. During this phase, the expression merely accesses the value of name from the customer bean, as is done in immediate evaluation. For a postback request, the JavaServer Faces

Without that fix,
