The web we want

I'm not a huge user of Firefox anymore. My exodus from IE brought me to Firefox, but then Chrome came along and I've been happy ever since.

That's quite analogous to my mobile telephone experience - starting with Nokia, big jump to first generation iPhone, now happy with Android.

I still use Firefox, but only so I can have a separate browser with an independent development builder session for Oracle APEX development. The FireFTP extension (more...)

APEX 101: Cascading Select Lists & Dynamic Actions

This post was inspired by a question on the OTN APEX forum, which contains requests for two fairly common scenarios:
1) A select list dependent on another select list
2) A report the updates based on the selections.

The original post submitted the page after each select change - APEX 4.x makes this unnecessaary thanks to cascading select lists.
And the report can also be refreshed without submitting the page thanks to Dynamic Actions.

So (more...)

Europa Report

Today I watched Europa Report - a movie that plays the same sport as Gravity, but seemed to go straight through to the keeper since I only heard about it while listening to a science podcast - which I think was StarTalk Radio hosted by the charismatic Neil deGrasse Tyson - of recent Cosmos fame.

Anyway - bloody brilliant movie. If you liked Gravity, you'll like this. And it does a fairly good (more...)

Thursday Thought: Are web clients getting thick?

I stumbled across this great post from a non-Oracle specific developer, and I thought I'd mention it here because it's worth a read.

http://zderadicka.eu/web-clients-are-getting-thick/

I've re-posted my comment here because they were thoughts rattling in my brain that I was going to rabble on about one day.
I've been thinking the same thing recently in regard to requests for Oracle APEX pages to not rely on connection to the database in order to operate (more...)

Shared authentication across multiple APEX applications

Quite a few times I see a questions regarding how to share authentication between Oracle APEX applications so the user does not need to log in a second time.

As long as your link between the applications share the session ID, the solution is simple - set the cookie name the same across your applications.
Shared components -> Authentication Schemes -> Edit current scheme -> Session cookie attributes -> Cookie Name
Set same cookie (more...)

Adding CSS buttons to your report

I've liked this concept ever since I saw the packaged applications use this technique:


I've finally gotten around to posting this in part due to some feedback on my sample application.

I used Chrome's inspect element tool to extract the CSS required to create this effect.
According to my notes I first did this when the Bug Tracking application used Theme 24.

You can then modify this to suit your requirements. I've changed the buttons (more...)

Show APEX IR detail view by default

Since the Detail/Icon views were introduced to Interactive Reports in Oracle APEX 4.0, I've used the detail view a number of times to represent information in ways that don't even look like your standard columnar reports.

One example you may have seen was the original apexblogs.info - this was a detail view IR showing aggregated posts of APEX bloggers.
It's now hosted at odtug.com/apex and this appears to use an alternative method (more...)

APEX Shortcuts Use Case

Recently Martin described APEX Shortcuts, a shared component that I don't often use - and probably even less now.

APEX wizards create them for the delete process in forms, but I thought I'd describe an example of how you might use one for your own needs.

The sole purpose I've used them is to generate HTML text from PL/SQL - often for links to appear near text items. For example, you could use them (more...)

Off topic – 2014 predictions

Here are my predictions for 2014.

I realise that traditionally yearly predictions are made in the first month of the Gregorian calendar year... but I've been busy. So I'm going to make some predictions in my birthday month and see how things eventuate over the next 12 months. Many sites do this over the new year, and I do love the commentary when one looks back over the previous 12 months. It's amazing, well not (more...)

Advert: Packt celebrates 2000 books

No APEX5 blog post today, but it turns out today is the final day of Packt Publishing celebration of 2000 titles since their first book was published in 2004.
I like puns
I have the honour of being one of these titles with my Oracle APEX Techniques video series, and I've had the pleasure of reviewing a number of their books.

They have a buy one get one free offer but it ends today - (more...)
