Updateable IR...at least sort of ..(a.k.a calling an On Demand Process on a Public Page)

On apex.oracle.com I created an example of an updateable Interactive Report. It is not an in-line update functionality, but you can click on an image and so update the status of a record. It is not rocket science but a nice way to present such a functionality to your end users.
But while creating the example I discovered that the example worked on a Page that requires Authentication, but didn't work on an Public Page... To call the On Demand Process I used the namespaced function apex.ajax.ondemand, instead of the more or less old-fashioned htmldb_Get. But unlike the htmldb_Get, apex.ajax.ondemand has no parameter for the page where the process should run (actually apex.ajax.ondemand passes '0' as the page parameter to htmldb_Get). So in order to get things working I needed to mark Page 0 as Public also...
I guess it would be a nice enhancement if you could either pass a page parameter to apex.ajax.ondemand (default 0 is acceptable) or it should use the current page ($v('pFlowStepId')) as a default. Then you don't need to mark Page 0 as Public also. And I want as less Public Pages as necessary...

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!

Dockerize your APEX development environment

Nowadays Docker is everywhere. It is one of the main components of Continuous Integration / Continuous Development environments. That alone indicates Docker has to be seen more as a Software Delivery Platform than as a replacement of a virtual machine.

However ...

If you are running an Oracle database using Docker on your local machine to develop some APEX application, you will probably not move that container is a whole to test and production environments. Because in that case you would not only deliver a new APEX application to the production environment - which is a good thing - but also overwrite the data in production with the data from your development environment. And that won't make your users very excited.
So in this set up you will be using Docker as a replacement of a Virtual Machine and not as a Delivery Platform.
And that's exactly the way Martin is using it as he described in this recent blog post. It is an ideal way to get up and running with an Oracle database …
