OOW16: What is new in ADF

It was not hard to find the ADF sessions this year at Open World, mainly because there was really only one session. Shay his session about new features in JDeveloper & ADF. It was worth seeing who would show up in the room and to be honest, it was quite crowded for an ADF session. 

JDeveloper 12.2.1.1.0 came out in June 2016, however, this new JDeveloper is only a Patch Set, so mainly bug fixes and not much news compared to last year. Last year I already wrote a blog entry about the JDeveloper 12.2.1.0.0.

ADF Business Components Triggers

These are simple hook points, in both the Entity Object level as wel as the View Object level, just like we know from the database. You can for example create a BeforeDelete trigger or an AfterInsert. 

You can write this in groovy, JDeveloper even has syntax support for that now and will also do a type check on the groovy code.

ADF Remote Regions

The ADF Remote Regions were already in JDeveloper 12.2.1.0.0 as well, however, you might have done a small Proof of Concept and came to the conclusion not to use this. Well, the latest patch set included a lot of bug fixes on the remote regions, so if you ever had a good usecase for this it might be worth reconsidering. 

New DVTs

There are again some new Data Visualisation Tools as well:

Next Release

There was a little bird saying something about 12.2.1.2.0, however, I could not find anything official on this, so we have to sit tight wether we will get an other PatchSet or a release.

OOW16: Oracle JET

Since last year at Open World, the Oracle JET team has been quite busy and it has been for the better. There has been quite some development, some great blogs and even a free online course (MOOC). A quick update of the cool features I have seen.

First of, lets start easy, you can see how your layout looks on different devices. No rocket science and not something shockingly new, but pretty cool they now support this.

When in the Cookbook, you can select the device on the top right, and you will see the preview directly in your browser.

Next to that, they have redone the Cookbooks, so the page looks new and refreshing, but that is not all, there is a new section 'Composite Component', in Cookbooks you can find it under Framework:

In here they introduce the concept of CCA: Composite Component Architecture. The concept of writing reusable pieces of UI, that can be embedded as an HTML element. This might sound familiar, this is something HTML5 and web components try to achieve as well.
The good news is that JET can now create HTML5 web components and even better, Oracle will put effort in making all current available JET components into HTML5 Web Components.

JB has created a cool example of how that can work. If you go to the advanced tab of the Composite Component page, you will see a memory game, like this:

You can find all the code to create this component on this page, however you can also consume it as a web component. JB explains this on his github account as well, you can see how the development effort will go down, mixing different JET components. After installing, when consuming the web component for the memory game, this is all the HTML code needed to embed on your webpage:
