One of my talented colleagues discovered an interesting ADF logic bomb which I thought I'd share here. The issue is with the instantiation order of ADF Faces scoped beans in JDev 11g when using Bounded Task Flows embedded as regions in another page.

There’s a rather obscure JDeveloper bug that only effects IE7, for af:columns in af:tables that show af:outputText fields based on dates that are null (phew, try and say that with a mouth full of wheaties). It occurs in 11.1.1.4.0 and 11.1.2.0.0 (and all versions in between it’s assume...
Within JDev 11g+ experienced ADF programmers will be familiar with PageFlowScope beans used by tasks flows, in particular Bounded Task Flows (BTFs) where they provide the equivalent of session scope for variables for the life of the BTF for a specific user session. Indeed the Oracle do...
With the huge amount of sessions at Oracle Open World, it’s often hard to find the little gems of information amongst all the marketing. This is true of ADF like all other technologies at the conference, there’s simply a lot of information to digest and filter. Luckily Oracle 
Thanks to everyone involved with this week’s videos – Andy, Chris, Matt, Ron, Keith, Calvin and Jonathan. I try to recall all the various things we covered this week and wrap up Oracle Open World 2011.
From time to time in JSF and ADF Faces RC applications there’s the need from one managed bean to retrieve another, typically from a lesser scoped bean to a greater, such as a requestScope bean retrieving a sessionScope bean to access its methods. There’s essentially 3 avenues to solvin...
There are very few pieces of software where a casual approach can be taken to the process of software development. Software development is intrinsically a difficult process, gathering requirements, design, development and testing all taking large effort. In reaction enterprises have se...
ADF's af:showDetailItem tag is used as a child to parent tags such as the af:panelAccordion and af:panelTabbed. JDeveloper's online documentation states the following about the af:showDetailItem tag:
The showDetailItem component is used inside of a panelAccordion or panelTabbed compon...
The previous blog post in this series looked at the default behaviour of the ADF framework in 11.1.1.4.0 of the af:region tag embedded in a af:showDetailItem tag. In this post we'll look at programmatically controlling the activation of regions to stop unnecessary processing.
This exa...
The previous blog posts in this series (part 1 and part 2) looked at the behaviour of the af:region tag embedded in a af:showDetailItem tag with JDeveloper 11.1.1.4.0. This post investigates the changing nature of the "deferred" activation property for the underlying af:region task flo...

There is an old saying: Respect and Suspect.
When someone declare, write or say something, do not decry or ignore him - respect him. It may turn out that the information he provides is valuable or useful.

The EXISTS keyword in SQL queries is an efficient mechanism for returning record sets from one dataset when they exist in another dataset. For example we can write queries like:
We all remember the Internet bubble back in 1999-2000 era. Start-ups were getting huge valuations. The joke then was – if you are 27 years old and not a millionaire, then you are a failure. All you needed was a sign-board saying “new internet company” and stand on Sand Hill Road. Sever...
ADF Libraries are a very useful feature of JDeveloper 11g. They allow a master application, via the Resource Palette, to load Bounded Task Flows (BTFs) and the BTF's associated ADF Business Components from separate applications, without having to include the BTF and ADF BC objects in ...
This is a very common task that most application/database developers come across; testing various datatypes of a database. Honoring the principle DRY, here is a template with ddl for table creation (covering most data types) across various databases.

Inter Bounded Task Flows (BTF) communications are aided in JDeveloper 11g by the use of contextual events, a BTF publish-subscribe mechanism for passing data between BTFs. Yet in some situations contextual events may be the equivalent of "using a sledge hammer to crack a nut", where de...

Sometime back I blogged about Stress & load testing web applications (even ADF & Apex) using Apache JMeter. That post dealt with the generic setup of recording a web session and then replaying under load via JMeter.
