Collecting ideas for APEX 4.0 Plug-Ins...using Google Wave

As you all know by now APEX 4.0 will have some new functionality regarding the creation of Custom Item Types and Custom Region Types. These types will be called "Plug-Ins". The idea is that there will be a public App Store like library where you can up- and download plug-ins.

A snippet from the Oracle Open World APEX 4.0 presentation:
  • Easy way to enhance the existing built-in functionality of Oracle APEX with new item types, region types, dynamic actions, etc.
  • Developers use in similar fashion to native widgets
  • Wizard support and declarative setting of attributes
  • Included in APEX application export
  • By providing this plug-in system in APEX, we want to engage the APEX community to create a rich ecosystem around Oracle APEX.
The APEX Development Team can’t possibly incorporate all the widgets that developers would like to utilize. By using plug-ins developers can readily incorporate additional item / region types to enhance the functionality, appearance and user friendliness of their applications. Once defined, plug-in based components are created and maintained very much like standard APEX components. We believe that the APEX community will build many plug-ins and make them available to others. Much like with the SQL Developer plug-ins it will be up to the contributors whether these are freeware, etc.

In the demo the APEX Dev Team is showing an Amazon style 'star rating' (as an Item Type Plug-In). (like the image above)

So maybe now is time to gather ideas for Plug-Ins (using this cool collaboration tool). So don't be shy and add your ideas about the Plug-Ins you think you could use (or even create yourself !) or are just very cool....

Custom Item Types
  • Amazon like star rating
Custom Region Types
  • Google Wave
  • Google Visualizations
So please add your own ideas to this wave, and let's make collaboration happen...

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

A review of APEX World 2017 - Day 1

Last week the SS Rotterdam was the beautiful location of the largest gathering of APEX Developers worldwide. With around 380 (!) attendees a new high was set. And they came from all over the world : I spotted people from The Netherlands, Belgium, Switzerland, Austria, Croatia, Germany, Denmark, Norway, UK, Ireland and the USA. And I even might have missed one or two ….

The event started with a presentation by the “father of APEX”, Mike Hichwa, talking about "Oracle APEX Past, Present and Future”. Of course everyone is curious what the APEX future might bring: Friendly URL’s, automated testing, more JSON, concurrent APEX versions, third party Oauth 2 authentication (think Facebook, Google), APEX app diff and more, a lot more, REST capabilities. And now we have to wait for APEX 5.2 … and that might take a while! 
After this keynote, the conference split up in three tracks. After the coffee break I returned to to big theatre where Geertjan Wielenga talked about "Finally Javas…

Push changed rows to an Interactive Grid

For pushing changes from the database to the end user, the regular solution is using websockets. A change in a record is detected - using a trigger or using the CQN (Change Query Notification) feature - and a notification is send to a websocket server. That websocket server broadcasts the notification over a channel to all browsers that are tuned in to that websocket channel. Then the browser reacts to that notification, usually showing an alert or refreshing a report. This trick is described on multiple sites, just Google for "oracle apex websockets" or similar.

So back in the old days, we used that notification in the browser to refresh the (interactive) report. But along comes the Interactive Grid (IG). While he full-refresh mechanism still works for IG, an IG has also the option to refresh just one row.  So wouldn't it be awesome that just the changed row(s) get refreshed upon a change in the database, instead of the whole report? Can we do it ... yes we can!
