Coloring side menu entries
Sometimes you want to add a little more color to the navigation menu. The idea in one project was to use colors for certain areas in an application. The color would show the user where he is currently working. Whether such colors are a feature that end users like, is still part of an ongoing discussion. But here are the technical details how to implement it.
The example uses a very small apex application that I’ll be using for a DOAG2015 presentation “Exotic SQL” (http://syntegris-doag.de/#vortraege).
Steps to create this
I explain the changes in detail a little further down.
- Create a new List template based upon the current one.
- Switch the user interface from the old to the new template

I can not guarantee that you never heared of this. But the majority of developers doesn’t know or doesn’t seem to know. And honestly – most of this information is fairly useless – and mostly harmless.

I’ve had quite a few discussions with people regarding whether APEX running inside the database is a good thing or a bad thing. Personally I believe it is definitely a good thing, I see no downsides really. However a recent forum thread
For me, the fact that APEX runs inside the database means that one of the major positives is you are able to take full advantage of each and every database available to you. A recent forum thread illustrates this very nicely. The poster in the thread has deleted some files and has unfortunately performed a commit before realising their mistake.
Here is where the features of the database can help you, for example we are able to take advantage of the Flashback feature to get the database back to the state it was in before the files were deleted.
The user in the forum deleted some files from…
