The immediate <\/strong>attribute in JSF is commonly misunderstood. If you don’t believe me, check out Stack Overflow<\/a>. Part of the confusion is likely due to immediate <\/strong>being available on both input (i.e.. <h:inputText \/>) and command (i.e. <h:commandButton \/>) components, each of which affects the JSF lifecycle differently.<\/p>\n

Here is the standard JSF lifecycle:<\/p>\n

<\/div>\n
\"\"<\/a><\/div>\n

For the purposes of this article, I’ll assume you are familiar with the basics of the JSF lifecycle. If you need an introduction or a memory refresher, check out the Java EE 6 Tutorial – The Lifecycle of a JavaServer Faces Application<\/a>.<\/p>\n

Note: the code examples in this article are for JSF 2 (Java EE 6), but the principals are the same for JSF 1.2 (Java EE 5).<\/em><\/p>\n

immediate=true on Command components<\/h2>\n

In the standard<\/em> JSF lifecycle, the action attribute on an Command component is evaluated in the Invoke Application<\/strong> phase. For example, say we have a User <\/strong>entity\/bean:<\/p>\n

public class User implements Serializable {\r\n @NotBlank\r\n @Length(max = 50)\r\n private String firstName;\r\n\r\n @NotBlank\r\n @Length(max = 50)\r\n private String lastName;\r\n\r\n \/* Snip constructors, getters\/setters, a nice toString() method, etc *\/\r\n}<\/pre>\n
And a UserManager <\/strong>to serve as our managed bean:<\/p>\n
@SessionScoped\r\n@ManagedBean\r\npublic class UserManager {\r\n private User newUser;\r\n\r\n \/* Snip some general page logic... *\/\r\n\r\n public String addUser() {\r\n  \/\/Snip logic to persist newUser\r\n\r\n  FacesContext.getCurrentInstance().addMessage(null,\r\n    new FacesMessage(\"User \" + newUser.toString() + \" added\"));\r\n\r\n  return \"\/home.xhtml\";\r\n }<\/pre>\n
And a basic Facelets page, newUser.xhtml<\/strong>, to render the view:<\/p>\n
<h:form>\r\n <h:panelGrid columns=\"2\">\r\n\r\n  <h:outputText value=\"First Name: \" \/>\r\n  <h:panelGroup>\r\n   <h:inputText id=\"firstName\"\r\n    value=\"#{userManager.newUser.firstName}\" \/>\r\n   <h:message for=\"firstName\" \/>\r\n  <\/h:panelGroup>\r\n\r\n  <h:outputText value=\"Last Name: \" \/>\r\n  <h:panelGroup>\r\n   <h:inputText id=\"lastName\" value=\"#{userManager.newUser.lastName}\" \/>\r\n   <h:message for=\"lastName\" \/>\r\n  <\/h:panelGroup>\r\n\r\n <\/h:panelGrid>\r\n\r\n <h:commandButton value=\"Add User\" action=\"#{userManager.addUser()}\" \/>\r\n<\/h:form><\/pre>\n
Which all combine to produce this lovely form:
 
<\/div> <\/div><\/p>\n
\"\"<\/a><\/div>\n
When the user clicks on the Add User<\/strong> button, #{userManager.addUser}<\/strong> will be called in the Invoke Application<\/strong> phase; this makes sense, because we want the input fields to be validated, converted, and applied to newUser before it is persisted.<\/p>\n
Now let’s add a “cancel” button to the page, in case the user changes his\/her mind. We’ll add another <h:commandButton \/> to the page:<\/p>\n
<h:form>\r\n <!-- Snip Input components --> \r\n\r\n <h:commandButton value=\"Add User\" action=\"#{userManager.addUser()}\" \/>\r\n <h:commandButton value=\"Cancel\" action=\"#{userManager.cancel()}\" \/>\r\n<\/h:form><\/pre>\n
And the cancel()<\/strong> method to UserManager<\/strong>:<\/p>\n
public String cancel() {\r\n newUser = new User();\r\n\r\n FacesContext.getCurrentInstance().addMessage(null,\r\n   new FacesMessage(\"Cancelled new user\"));\r\n\r\n return \"\/home.xhtml\";\r\n}<\/pre>\n
Looks good, right? But when we actually try to use the cancel button, we get errors complaining that first and last name are required:<\/p>\n
\"\"<\/a><\/div>\n
This is because #{userManager.cancel}<\/strong> isn’t called until the Invoke Application<\/strong> phase, which occurs after <\/em>the Process Validations<\/strong> phase; since we didn’t enter a first and last name, the validations failed before #{userManager.cancel}<\/strong> is called, and the response is rendered after the Process Validations<\/strong> phase.<\/p>\n
We certainly don’t want to require the end user to enter a valid user before cancelling! Fortunately, JSF provides the immediate <\/strong>attribute on Command components. When immediate <\/strong>is set to true on an Command component, the action is invoked in the Apply Request Values<\/strong> phase:<\/p>\n
\"\"<\/a><\/div>\n
This is perfect for our Cancel use case. If we add immediate=true <\/strong>to the Cancel , #{userManager.cancel}<\/strong> will be called in the Apply Request Values<\/strong> phase, before any validation occurs. <\/p>\n
<h:form>  \r\n <!-- Snip Input components -->\r\n\r\n <h:commandButton value=\"Add User\" action=\"#{userManager.addUser()}\" \/>\r\n <h:commandButton value=\"Cancel\" action=\"#{userManager.cancel()}\" immediate=\"true\" \/>\r\n<\/h:form><\/pre>\n
So now when we click cancel, #{userManager.cancel}<\/strong> is called in the Apply Request Values<\/strong> phase, and we are directed back to the home page with the expected cancellation message; no validation errors!<\/p>\n
\"\"<\/a><\/div>\n

\n<\/strong><\/h2>\n
What about Input components?<\/strong><\/h2>\n
Input components have the immediate <\/strong>attribute as well, which also moves all their logic into the Apply Request Values<\/strong> phase. However, the behavior is slightly different from Command components, especially depending on whether or not the validation on the Input component succeeds. My next article will address immediate=true<\/strong> on Input components. For now, here’s a preview of how the JSF lifecycle is affected:<\/p>\n
