Self Serve Training Ajax Push Ajax Push allows the application to incrementally update any part of the page at any time, for any group of clients. This is a small change in terms of the technical capabilities of Ajax applications, but it is a revolutionary change in terms of what applications can actually provide to users. Ajax Push is the key to building collaborative, multi-user applications for the web. It is, however, useful to understand the basic mechanics.

Sanris Log in to post a comment. For example, selective content presentation, based on application state, becomes easy to implement. Icefacws client-side Ajax bridge provides a convenience function for tying JavaScript events to the partial submit mechanism. This may be the desired scope for some states, but typically, presentation-related state is more appropriately kept in request scope.

By implementing these JavaScript callbacks application developers can create custom indicators and reactions for these events. ICEfaces brings value to any Java EE development project that needs to provide superior presentation capabilities to the icsfaces application user. Armed with incremental Direct-to-DOM rendering, you can begin to imagine a more dynamic presentation environment for the user.

Synchronous and Asynchronous Updates 9. The visual design time is functional, but does not have the same level of polish as Visual JSF Woodstock. Responsible for managing all blocking and non-blocking requests after initial page rendering. ICEfaces-specific capabilities such as partial submit can be configured into the tag through the standard JavaScript-specific pass through attributes e.

Optimizing Server Memory Consumption Instead, you can consider fine-grained manipulation of the page to achieve rich effects in the application. Perhaps you would like the login button to stay disabled until you have values for both the username and the password. Table 3 shows a summary of the Managed Bean Scope. Click here to see the current ICEfaces release documentation 3. This is currently the recommended inclusion mechanism with this ICEfaces release.

Standard JSF applications can only deliver presentation changes in response to a user-initiated event, typically some type of form submit. This feature can be disabled by specifying the following configuration parameter in the web. The default upload directory specified via the configuration parameters above can be overridden on a per-instance basis via the uploadDirectory and uploadDirectoryAbsolute attributes on the ice: I will surely use it and give feedback! ICEfaces 4.

Provides a comprehensive set of rich JSF components that leverage Ajax features of the bridge and provide the basic building blocks for ICEfaces applications. Liferay in Action — Project Kenai 1, views pages. There are some compatibility issues around JSF 1.

In addition, the Rime and XP themes also include alternate stylesheets rime-portlet. See Adding and Customizing Effects, p. The standard JSF validator mechanism can be leveraged, or any other arbitrarily complex or simple evaluation logic can be icefces. Support for NetBeans 6. More From Alex Evang. Synchronous update mode can be enabled application-wide using the ICEfaces context parameter, com. Most Related.

Nikozragore With concurrent DOM views enabled, each browser window is distinctly identified with a view number and DOM updates will be correctly applied to the appropriate window. Development and Deployment Considerations Figure 6 Synchronous Updates One serious deficiency with synchronous updates is that the application requires a client-generated request before it can affect presentation layer changes. To specify the directory location where uploaded files are stored, the following parameter is used: Provides a comprehensive set of rich JSF components that leverage Ajax features of the bridge and provide the basic building blocks for ICEfaces applications. ICEfaces overcomes this deficiency with an asynchronous update mode that facilitates driving asynchronous presentation changes to the client, based on server-side application state changes.



Different menu options are presented to the user, depending on the state of the item, thus making the menu component truly dynamic. The application itself is composed primarily of one ace:dataTable component and one ace:menu component. The data table is used to display the to-do items and their properties and also to allow sorting and selection of the items. The menu component will present different actions for the item that is currently selected in the data table. Setup The application only consists of one bean, one data object i.
