jQuery Toggle Image

For this, you will need two lines of code.

jQuery – Replace Image

I am posting this just because I am getting questions related to this or similar issues all the time. In this example you can see how you can replace images in your page using Dynamic Actions. There are at least two good ways to do that:

1. Rendering images in a report. Refreshing a report is a predefined event in a Dynamic Action and doesn't require coding.


2. Using jQuery to do that.


Tabular Form – Change Column Type

Just started a new version of My Demo Application - based on APEX 5.0 and Universal Theme. There, I will rework the old content and provide some interesting new possibilities (as of 4.2). In this example I am showing how to change the column type from Text to Display (Saving State) in a tabular form.

APEX 5.0 – PL/SQL Function Returning Error Text – Bug 20971572

I prefer using PL/SQL Function Returning Error Text while creating validations. Two days ago I discovered a bug - it is not possible to create the function if no error message entered. This bug has been documented and will probably be fixed in 5.1. The workaround is to enter a dummy text like "ERROR" or similar.

APEX 5.0 and Standard Report Column

If you are using the new Page Designer in APEX 5.0, you may search for the "Standard Report Column" in the list of column types. If you switch to the component view, you will see it. In the Page Designer you don't have the old column types any more. You should choose "Plain Text" and activate the option "Escape special characters" on the bottom of the column options.

Expert Oracle APEX 2nd Edition

Just submitted first of my two chapters (Tabular Forms) for the new Expert Oracle APEX 2nd Edition. The chapter is covering the most important practices in Tabular Form handling. Also, a couple of neat features like cascading select lists in Tabular Forms - this time using standards only. Still not sure when the book will be published but it should happen soon.

APEX im Jahr 2015

Mit dem erscheinen von APEX 5 dreht die Community jetzt so richtig auf.

Neben der APEX Connect im Juni (bis 08.05. Frühbucherrabatt) wird es schon einen Monat später eine Reihe von APEX 5 Webinaren unter dem Motto #apexsummer15 geben.

Was mir bei den ganzen Aktivitäten auffällt, ist der starke Community Faktor. Umso mehr wundert es mich, dass sich nach Veröffentlichung von APEX 5 keine große IT-News Plattform intensiver mit der Materie befasst (more...)

Destroying The Moon

Just under three years ago, I joined Enkitec when they acquired Sumneva.  The next three years brought a whirlwind of change and excitement - new products, additional training, and expanding the APEX practice from an almost nonexistent state to one of the best in the world.

Like all good things, that run has come to an end.  Last Friday was my final day at Accenture, and I am once again back in the arena of (more...)

Oracle APEX 5.0 released today

After 2.5 years of development, today is the day APEX 5.0 is publicly released and ready to be downloaded to install on your own environment.

In my view it's the best release ever. Not so much of the new Page Designer - although that is definitely a piece of art and it increased productivity even further - but because it's the first time whole of APEX got refreshed and every piece was put (more...)
