APEX IG Cookbook Update for 18.2

Last week I presented Interactive a Grid Deep Dive for APEX Office Hours where I demonstrated a new version of the IG Cookbook.
The video and slides are now available. The presentation covered important aspects of the Interactive Grid architecture. As promised I’m making the latest IG Cookbook (release 4.0) for APEX 18.2 available for download. As always make sure you install the Sample Interactive Grids app first because it creates some needed tables.

There are many exciting additions and improvements.

APEX 18.1 New Region Features

Note this is about a future release of APEX and the final release may differ from what I describe.

Last month I gave two talks at the NL.OUG APEX World conference. The first was part of the APEX 18.1 new features presentation with Anthony and Shakeeb. There I showed an app that demonstrated new region features. I said I would make the app available. Now that apex.oracle.com has been upgraded to 18.1 pre-release you have somewhere to try it out. You can download New Region Features (18.1). Note: You must install the Sample Interactive Grids app and Sample Charts app first because it uses sample data from those apps.

APEX 18.1 jQuery, jQuery UI, and JET upgrade

Note this is about a future release of APEX and the final release may differ from what I describe.

You’ve read the announcements, you’ve seen the presentations, you signed up for the early adopter, and gave feedback and now you think there is nothing to do but sit back and wait for 18.1 to be released – no no no. In this article I will tell you what you need to do to prepare for the jQuery, jQuery UI, and JET library upgrades in the upcoming APEX 18.1 release (was 5.2). This applies to apps and plug-ins. If you wrote an APEX plug-in that you have shared with others be proactive and make sure it is ready for 18.1.

APEX 5.2 Interactive Grid

Note this is about a future release of APEX and the final release may differ from what I describe.

As of this writing Application Express release 5.2 [Update: the release is renamed 18.1] is a work in progress but you can be an early adopter. Try it out and give us feedback. My experience working on APEX 5.2 has been quite different from 5.1. In the previous release I, along with a few others were laser focused on Interactive Grid. In contrast my work on 5.2 feels like a flood light shinning on many area, some not even identified during release planning. In this series of articles I give my perspective and some technical details on things that I have worked on. Lets start with Interactive Grid.

APEX IG Cookbook for 5.1.4

Happy New Year. I wanted to get this IG Cookbook update out the same week that APEX version 5.1.4 was released and Early Adopter for 5.2 came out but a technical problem (described below) and the holidays slowed me down. I will have some things about 5.2 EA to blog about soon. Download IG Cookbook release 3.0. As always make sure you install the Sample Interactive Grid app first because it creates some needed tables.

Visibility and Size Managed Components

For no particular reason other than I feel like writing about it, I’ll now describe some minor functionality that crept into the APEX 5.1.1 patch release. Typically a patch release shouldn’t and doesn’t have any new functionality but sometimes there is no better way to fix a bug. This topic is for the advanced plug-in developer and anyone curious about the internal details of APEX JavaScript. No screen shots, no demo app, no sample code, just raw information; sorry.

APEX IG Cookbook Update

Here is an update (revision 2) of the Interactive Grid Cookbook. You can download it here. This revision adds an example of reordering rows. This has been asked for on the APEX discussion forums. The example is a task list editing page.

The example also shows a workaround for the “no data found” error that can happen when saving data if the SQL statement has a where clause. When the IG SQL statement has its own where clause, such as “... where EXAMPLE_COL = :P1_CURRENT“, if the column is editable and the user changes the value so it no longer matches the where expression you get the error. The reason is that as part of saving the data the IG Automatic Row Processing (DML) process tries to get the latest values for edited records and if a record is now out side of the result set because of the where clause you get the error. A number of people have run into this problem.

Feel free to discus the techniques shown in this app or issue with this app on the APEX Discussion Forum. This is not an officially supported sample but I’ll reply if possible and you can all help each other as well.
