Using dynamic tooltips in your Interactive Report


Inside an Interactive Report (IR) I had a comment column. The comments in this column could become really large and the users wanted the comments to be automatically trimmed if more then 60 characters were displayed. If the user moved the mouse above a trimmed comment then a tooltip should be display including all comment text.

My first idea was to check for existing plugins which could do this job for me. So I searched (more...)

Crowdsourced software development experiment

A few days ago I got an email about an experiment how to program with the crowd.

I didn't really heard about it before, but found it an interesting thought. In this experiment people will perform microtasks (10 minutes task), as a member of the crowd. People don't know each other, but will collaborate together. The system is distributing the work and supplies instructions. The challenge is in creating quality code that meets the specifications.

My "Must See" ADF/MAF Sessions at KScope 16

Yes, you read that right - it's not a typo, nor did one of my kids or wife gain access to my laptop.  It's part of a "blog hop" - where a number of experts made recommendations about KScope sessions that are "must attend" and are not in their core technology.  I picked ADF/MAF, as I don't have any practical experience in either technology, but they are at least similar enough that I would not (more...)

Please, use HTTPS for your APEX apps

Why use HTTPS?

When you Google this question you get many different answers, but this answer of Google Developers answers it for me in short (click the link for more details):
  • HTTPS protects the integrity of your website/APEX app
  • HTTPS protects the privacy and security of your users
  • HTTPS is the future of the web; many new technologies only work with https (for example Service Workers; you can read more about Service Workers and APEX (more...)

The APEX CONNECT and the APEX dashboard competition 2016

Before I tell you about the APEX dashboard competition winner I want to share my impressions from the APEX CONNECT 2016 in Berlin with you.

We had 3 days fully packed with APEX, SQL, PL/SQL, SQL Developer and different JavaScript technology topics.

In every way Niels de Brujin, Carsten Czarski, Christian Schwitalla and the whole DOAG team created an amazing event and has raised the quality compared to the last year.

We had more attendances, (more...)

Web technology in APEX Development

How did you get started with developing your first APEX app? 

My guess is either you went to https://apex.oracle.com and got a free account or Oracle Application Express was already in your company and somebody told you the url you could connect to. For me that is really the power of APEX, you just go to an url and within minutes you created your first app.

Staying within the APEX framework?

My Presentation at APEX Connect 2016

On 28th of April I will be presenting at APEX Connect in Berlin. The topic is Integration of APEX with HERE Maps. If you are interested to see how you can integrate APEX with Maps (HERE or Google or some other) please join the presentation. The best thing is that this integration ist done using APEX Plugins only. I will try to show as many functionalities as possible including Routing, Tracing, Positioning and a combination (more...)

An Important Change Coming for Oracle Application Express in Oracle Database 12cR2

A minor but important change is happening for Oracle Application Express in the forthcoming Oracle Database 12cR2.  Specifically, Oracle Application Express will not be installed by default in the Oracle Database.  This change was made specifically at our request.  We thought the pros far outweighed the cons, and we thought this was good for our customers and consistent with our recommendations.


Pros

  1. Provides flexibility for a DBA to run multiple APEX versions in an Oracle (more...)

My Demo Application

If you experience a problem accessing My Demo Application (old and new version) at apex.oracle.com, that means there is a reason for that. One of the users deleted all the applications in my workspace and installed some of his own. I don't think this was intended but it is still a lot of work and I am trying to geta all the important stuff back online. After that I will need to rethink (more...)

How to update a custom public theme in Oracle APEX

In the last post I showed how you can upload a custom theme to the instance repository so that all your developers can choose that theme within the create application wizard. And more importantly, subscribe that theme from the theme repository.

Now the next question is how to update that public theme so that all applications can inherit the changes.

My first attempt was to simply go to Instance Administration – Manage Instance – Public (more...)

Creating a custom public workspace theme

The Universal Theme introduced with APEX 5 is immensly good looking and comes with a powerful Theme Roller to customize it.

With that new theme most, if not all, older themes are obsolete.

That leaves us just with a few corporate designs which can’t (or don’t want to) be replaced by the UT.

Now ideally you want your developers to use that custom theme in all applications and also subscribe to that.
Historically I recommended (more...)

Me and the ODTUG Board

This afternoon my Twitter timeline exploded with retweets, likes and congratulations. It all started with this tweet:

So it's official now. As Sarah Zumbrum had to step down due to her (dream) move to Oracle, a position on the ODTUG board opened up. And I was asked whether I was still interested. And of course I was! So after an internal voting procedure, I received the good news last weekend - and had to keep (more...)
