Moving Elements in a Cascading Shuttle

Since APEX 4.0 cascading feature is a part of the standard. Not only a "normal" select list can be cascading but also a shuttle element. In this example I am showing how to filter a shuttle box and move the filtered values to the right side using just one click (change of the first select list).

CLOB Plugin

There is a new plugin available which makes it possible to save and render contents larger than 32k. This limitation was one of the most critical in APEX. I remember several projects where we had to create workarrounds to solve that issue. Now, there is no need to write your own code any more. Dan McGhan created a new plugin for that and you can find it here:

The current help regarding asynchronous submit is missing a detail at this point:

APEX Deep Linking, Authentication and Special Characters

It seem that there is a bug in APEX regarding deep linking, authentication and parsing special characters. See this thread. In this example I am showing a simple workarround which could be also applied in other similar situations where you need to transfer information using URL.

jQuery - my first functions

I still remember how hard it was to make something like this working before the APEX version 4.0. You needed to create a function and then attach it to each column in your tabular form. Debugging and making changes is the next issue you had to think about. Now, using jQuery it is just a two three simple steps solution with almost no hardcoding and tricks. Also, the number of code lines you need to write is quite moderate. See this example in my demo application:

Controlling Hide/Show Apex Regions Using Javascript

Hide/Show regions are very useful in that they allow users to hide certain on-screen content when it’s not relevant for them (and show it again just as easily) simply by clicking the small arrow icon in the top left of the region.

caveats

I always find myself putting an asterisk (if only mentally) next to certain statements. I shall now put all those statements here and link back.

Advanced Javascript Tutorial

Today I came across a great interactive tutorial which covers a series of advanced Javascript topics. It’s very well put together and lets you try out your own variations of the code being shown which can be very handy in making sure your understanding is correct.

It’s from John Resig, the creator of jQuery. The tutorial is not jQuery-centric though. In fact, it doesn’t talk about or use jQuery at all. It’s just pure Javascript.

How to make your browser save your password

Typically and for good security reasons the password manager from either Firefox or any other browser will not prompt you to save the password for the login screen of the APEX workspace or any of your own APEX applications.
