ADF Faces RC – Highlight partially refreshed areas to enlighten the user about automatic updates
One of the rich aspects of ADF Faces RC (and most Web 2.0/AJAX components) is functionality that performs Partial Page Refresh operations: actions by the user trigger asynchronous communication between browser and server that in turn may cause selected areas of the page to be refreshed. For example: entering a value may lead to a refresh of a derived value or a conversion of the entered value. Sometimes a single user action lead to refresh of multiple items and areas on the page. On other occasions, server push may cause items or page areas to be refreshed.
Without additional effort, these partial updates are subtle. They just happen. When the changes are small, the user will probably not notice the refresh taking place. He/she may see the new value, wondering where that came from. And that may be just fine. However, it could also be we like to make it clear to the user that and when items and areas have been refreshed. For example by highlighting the item or region in question immediately after the refresh takes place and having the highlight effect slowly fade away.
It turns out to be fairly easy to implement such a ‘highlight after partial refresh with fade away’ effect. More >
Oracle ADF 11g training
(note: click here for details in English about the AMISÂ 5 day ADFÂ 11g training)
Ga hier naar onze actuele  Oracle ADF 11g training.
In oktober kwam na bijna twee jaar van aankondigingen en previews de productieversie van JDeveloper en ADF 11g. Nu, op 20 april, vindt de première plaats van de ADF 11g training die AMIS in nauwe samenwerking met SAGE Computing Services, Australië (van ondermeer Oracle ACE Director Chris Muir) heeft ontwikkeld – op basis van een half jaar praktijkervaring volgend op anderhalf jaar aan experimenteren, onderzoeken en publiceren.
De training is gericht op ontwikkelaars die in de praktijk aan de slag willen gaan met ADF 11g. Wil je meer weten over deze training, ga dan naar 5-daagse ADFÂ 11g Training.
Ben je al ervaren met ADF 10g maar wil je wel graag met ADF 11g aan de slag? Dan kan je ook naar onze Masterclass ADF 11g Upgrade komen waarin we in één dag de nieuwe thema’s, functies en manier van werken met ADF 11g bespreken, in vergelijking tot de 10g release. Deze Masterclass vindt voor het eerst plaats op 14 april, in Nieuwegein en 18 mei, in Parijs (in samenwerking met Oracle University). Zie Masterclass ADF 11g Upgrade voor meer details.
How to declaratively instruct ADF Faces RC to partially refresh other components upon an event
ADF Faces RC has built in support for AJAX and Partial Page Refresh. Through the autoSubmit and partialSubmit attributes, we can indicate that a value change or an action (button or link click) should trigger an asynchronous request (PPR request). Through the partialTriggers attribute, we can configure components to be refreshed in any PPR request that is initiated by the a component whose Id is listed in the partialTriggers attribute. So you can say that through the partialTriggers attribute, we register a component as PPR listener on all components listed in the attribute value.
Sometimes, developers would like to be able to do it the other way round. To specify on a component X which other components should be refreshed when X is initiating a PPR request. In this article, we will discuss a method for doing exactly that. (more…)
