ODTUG: Thursday and the day after...

The last day of this great conference had "only" three presentation slots. The first one I attended, but honestly I didn't pay that much of an attention. I was writing my previous post at that time and I was rather familiar with the subject "Forms to APEX conversion". And I totally agree with the conclusions: Converting simple Forms is easy, but the more complex the Forms, the more work it will take to convert it to APEX!
The second one was called "APEX Stimulus Package". In fact it was more or less a list of things you have to consider to improve the performance of your APEX application - also due to the fact that most demo's didn't work because of a failing internet connection. 
To name some of the tips: Reduce images sizes and use png instead of gif or jpg; check the Apache log for errors and resolve them; add a favicon.ico; watch out with pagination schemes; tune your Page 0 processes; use Page and Region caching where appropriate; minify javascipt and css files; externalize javascript and css files; refactor PL/SQL etc. Some of the tips where obvious, some of them quite useful.
The last one of this week was rather cool. Roy McLean showed how to use Oracle Data Mining in combination with APEX. I never used the Data Mining stuff before, and you might need a degree in maths to use it properly, but the things you can do are rather amazing. For instance you can predict what probably will happen. As an example Roy showed a sort of Helpdesk application where a call was assigned to a certain (pool of) engineers by the text that you entered when describing the problem!
After the show was over I paid a visit to Obama's house, the Washington Monument and checked out the West side of The Mall.
The day after. Friday, I had until 10PM before my flight was leaving, so I visited the Capitol and "did" the East side of The Mall. The weather was fine (cooler than at home!) and it was good fun.
As in previous years I liked ODTUG very much - the best conference in the world. Hope to be there again next year in Long Beach, California.

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…

It's happening again ... running for the ODTUG Board of Directors 😉

For the third time in a row I'll be running for ODTUG's Board of Directors. But after ending as a runner up twice, I am sure I'm going to make it this time! But not without your help!

My campaign statement this year is:
I have been attending and presenting at Kscope conferences since 2007. This not only resulted in a vast amount of knowledge, but also - and even more important - a huge number of friends from all over the globe.  I want to see ODTUG grow and spread this community feeling even more! 
My experience as an attendee, presenter and content lead has provided the basic foundation to be a director. Next to that, my personality and (global) network will be beneficial to the whole board and organization. 
Since March I have served on the Board of Directors in a limited term for a Director who stepped down due to a career change. This has allowed me to have unique insight of all the things that are going on in and around the ODTUG organization. As the train was already ro…
