ADF Conference Season

Last week I attended OBUG Connect Conference, the Oracle Benelux User Group Conference. It was a great conference where I presented about the new to come ADF Mobile Framework. This is not yet Generally Available, but because of the good relationship with Oracle Productmanagement I was able to get hold of some very early sneak peaks so I could prepare a great presentation. I am not yet able to share anything in this post, however, feel free to contact me if you need to know more. I will see what I can do for you. As soon as I can share the presentation, I will host a link on my blog.

There is an oline photo impression of this conference, with a couple of photos of the presentation, and the live Fusion Middleware Development session.

Not only did I do my presentation, I was also part of the live Fusion Middleware Development team, next to Ronald van Luttikhuizen, Lonneke Dikmans, Steven Davelaar, Edwin Biemond en Lucas Jellema. An impression of this session can be found here.

Next month is all about preparing two sessions for ODTUG KScope 12, and writing papers for these presentations

The first session is about Reporting in ADF applications.

An ADF Special Report 
Oracle ADF is a very powerful framework for building enterprise applications. The framework, however, has no built-in solutions for reporting. In this session, you will learn how to fill this gap by using open source reporting solutions and solutions provided by Oracle.

The second one is about common UI patterns in ADF applications.

How to Bring Common UI Patterns to ADF 
When working with enterprise applications, you want to have the same user experience that you know from for instance office applications and browsers. People know how to use the features that can be found in browsers such as bookmarking, favorites, and working with tabs. The search mechanism provided by Google, that uses suggestions based on the text typed by the user, is so common that people expect this in every application. And there are more of these UI patterns. In this session, you will learn how to implement some of the common UI patterns in your ADF application.

I will keep you posted on this blog.

ADF 12.1.3 : Implementing Default Table Filter Values

In one of my projects I ran into a requirement where the end user needs to be presented with default values in the table filters. This sounds like it is a common requirement, which is easy to implement. However it proved to be not so common, as it is not in the documentation nor are there any Blogpost to be found that talk about this feature. In this blogpost I describe how to implement this.

The Use Case Explained
Users of the application would typically enter today's date in a table filter in order to get all data that is valid for today. They do this each and every time. In order to facilitate them I want to have the table filter pre-filled with today's date (at the moment of writing July 31st 2015).

So whenever the page is displayed, it should display 'today' in the table filter and execute the query accordingly. The problem is to get the value in the filter without the user typing it. Lets first take a look at how the ADF Search and Filters are implemented by the f…

ADF 12.2.x : Conditional Showing Message Instead of List of Values Popup

Today I had to fix an issue in one of our ADF applications. For those of you working with ADF (as I do too occasionally) this might be valuable, so I decided to share this. The application is based on an old Oracle Forms applications and I had to implement the following functionality:

FRM-41830 : List of Values contains no entries.

In other words (more ADF like) : If you are about to render a List of Values and that List of Values contains no rows, just show a message instead of showing the List of Values.

In this post I will describe how I was able to implement this although it turned out to be a challenge.
Below are the steps that I took. Note that the Application can be downloaded from GIT.

1) I use a UI pattern where we use readonly table and do edits in a popup. That means that any List of Values will add an additional popup to the UI.

2) The List of Values that I use in this sample only shows entries where the minimum salary is less then the employees current salary. Not that …

ADF 11g Quicky 3 : Adding Error, Info and Warning messages

How can we add a message programatically ? Last week I got this question for the second time in a months time. I decided to write a short blogpost on how this works.

Adding messages is very easy, you just need to know how it works.
You can add a message to your faces context by creating a new FacesMessage. Set the severity (ERROR, WARNING, INFO or FATAL ), set the message text, and if nessecary a message detail. The fragment below shows the code for an ERROR message.

1: public void setMessagesErr(ActionEvent actionEvent) {
2: String msg = "This is a message";
3: AdfFacesContext adfFacesContext = null;
4: adfFacesContext = AdfFacesContext.getCurrentInstance();
5: FacesContext ctx = FacesContext.getCurrentInstance();
6: FacesMessage fm =
7: new FacesMessage(FacesMessage.SEVERITY_ERROR, msg, "");
8: ctx.addMessage(null, fm);
9: }

I created a simple page with a couple of buttons to show the result of setting the message. When the butto…
