Ajax method supposed to be call, and print the new selected date. public void dateChangedAjaxListener() { I am curious about why you are not using the PrimeFaces Calendar control for this, however. An IDE is no. I am struggling to get an ajax listener to fire from within a p:inputText. xhtml is below with the offending section in red, context is that it is meant. I load new items without reloading my page with AJAX with this code: . and make it as a function to not repeat ourselves (for better maintenance and all, you know, right? What if we don't want to attach event every time AJAX is called? .. ".date-picker").datepicker({ autoclose:true, changeMonth: true.

That powerful reuse mechanism was, for the most part, rendered inconsequential in JSF 1 because it was so difficult to implement components. As you saw in Part 2however, JSF 2 makes it easy to implement components — with no Java code and no configuration — with a new feature called composite components.

That feature may very well be the most important part of JSF 2, because it finally realizes the potential of JSF components. In this third and final article on JSF 2, I will show you how to build on the composite-component feature by using the new Ajax and event-handling capabilities also introduced in JSF 2, with the following tips for getting the most out of JSF 2: Show progress In the first tip, I'll briefly review two components that I discussed at length in Part 2.

In the subsequent tips, I'll show you how to transform those components using Ajax and event-handling. Componentize The places application, which I introduced in Part 1contains a number of composite components. One is the map component, which displays a map of an address, complete with a zoom-level pull-down menu, as shown in Figure 1: The places application's map component A truncated listing of the map component is shown in Listing 1: That form submission triggers the JSF life cycle, which ultimately pushes the new value for the zoom level into the zoomIndex property of a location bean stored in the parent composite component.

That bean property is bound to the input component, in the first line of Listing 2. Because I didn't specify any navigation for the form submit associated with zoom-level change, JSF refreshes the same page after handling the request, redrawing the map image to reflect the new zoom level. However, that page refresh also redraws the entire page even though the only change is in the map image. AjaxifyI'll show you how to use Ajax to redraw only the image in response to a zoom-level change.

The login component Another component used in the places application is the login component. Figure 3 shows the login component in action: The login component Listing 3 shows the markup that created the login component shown in Figure 3: A login action method managedBean: A managed bean with name and password properties The managed bean specified in Listing 3 is shown in Listing 4: Using Groovy instead of the Java language doesn't buy me much in this case, other than freeing me from the drudgery of semicolons and return statements.

However, in Tip 2's Validation section, I'll show you a more compelling reason to use Groovy for the User managed bean.

Most of the time you'll want to configure login components fully with prompts and button text, as shown in Figure 4: A fully configured login component Listing 5 shows the markup that generated the login component in Figure 4: Listing 6 defines the login component: The loginAction attribute must be an action method that takes no arguments and returns a string. That string is used to navigate to the page the user sees after logging in.

This component's loginButton is accessible so that you can add action listeners to it, as depicted above. The class specified in f: In the next tip, under ValidationI'll show you how to add Ajax validation to the login component.

Partial processing and rendering JSF 2 supports partial processing and partial rendering by splitting the JSF life cycle into two distinct logical portions: Figure 5 highlights the execute portion: The render portion of the JSF life cycle View image at full size The idea behind the life cycle's execute and render portions is simple: The event that triggers the Ajax call A component to execute on the server A component to render on the client When the user selects an item from the zoom menu, JSF makes an Ajax call to the server.

When the Ajax call returns, JSF renders the map component, which uses the newly set zoom index to redraw the map, and now you have an Ajaxified zoom menu with the addition of one line of XHTML. But things can get simpler still, because JSF provides default values for the event and execute attributes. For menus, that event is the change event. In this example, that component is the menu, so I can also get rid of the execute attribute.

Of course, the preceding example is pretty simple: I am simply redrawing only the map instead of the entire page when the user selects a zoom level.

Some operations, such as validating individual fields in a form, are more complicated, so next I'll tackle that use case. Validation It's a good idea to validate fields, and provide immediate feedback, when a user tabs out of a field.

Even more, you're not supposed to save complete UIComponent instances in component's state.

Note that you can also use e. When the component is about to be rendered, the encodeBegin method is invoked which basically obtains the maxyear, minyear and value attributes and initializes the dropdowns. The first two attributes represent the maximum and minimum value of the "year" dropdown, which in turn defaults to respectively the current year and the maximum year minus Note that the value is obtained by the getValue method which is inherited from UIInput.

Finally the available values of the dropdown components are filled. The backing component will return the submitted value as a string in dd-MM-yyyy format. If you happen to use MyFaces instead of Mojarra, then you need to replace getSubmittedValue call on child component by getValue: This is needed because Mojarra and MyFaces don't agree on whether to process the UIInput component itself first before processing its children, or the other way round.

Mojarra first processes the UIInput component itself before its children, and therefore needs getSubmittedValue. MyFaces, on the other hand, first processes the children before the UIInput component itself, and therefore needs getValue. Shortly after getting the submitted value, JSF will invoke the getConvertedValue method, passing exactly the submitted value as 2nd argument.


Normally this method is not to be overridden and everything is delegated to default JSF Converter mechanisms, but the backing component has it overriden to take the opportunity to convert the submitted value to a concrete java. Date instance which will ultimately be updated in the model.

Note that no validation is performed and that's not necessary, because it's impossible for a hacker to provide a different submitted value than shown in the dropdowns e. Value is not valid on the associated dropdown. Finally, there's a "proprietary" ajax action listener method updateDaysIfNecessary which should update the day dropdown depending on the value of the month and year dropdowns, if necessary.
