After my initial post about this, I had a discussion with John Snyders of HardLikeSoftware fame, and it turns out there is a better and more efficient way to maintain the tree state. While what I outlined definitely works, what follows is the “preferred method” as it uses more of the built in interfaces. I have therefore implemented this version …
Maintaining APEX Tree Region Expansion State
As soon as I was finished with the first incarnation of the ORDS REST Workshop for release in APEX 18.1, I had a list as long as my arm of things that I wanted to do to improve it. Some small, some large. One of the things that bugs me the most is that the APEX Tree region on the …
Warning APEX Users of Form Changes on Navigation away from the page.
It has come to my attention the the link back to this article that originally appeared on the Enkitec.com web site is broken.

Refreshing Flash Charts with AJAX.

Therefore it is likely not supported, so use at your own risk! ————————– Yesterday, I ran across this post on the OTN APEX Forums. The problem was basically this. Say you have a chart which you want to refresh each time someone …
Warning a user that the form has changed he navigates away without saving.
For those of you who haven’t visited the new Sumneva.com site, here’s an excuse. We’ve added a Tips & Tricks section on the Support tab where we will be sharing little tid-bits of information that we learn as we work with APEX.

JavaScript and Dates.
If you’ve ever tried to work with date manipulation and formatting in JavaScript, then you know what a hassle it can be. While trying to solve a particularly itchy problem with dates, I ran across this post by Steven Levithan that everyone should be aware of. He’s put together a very nice little Java Script library that lets you format …
