JDeveloper allows to easily create tables with the af:table component. The table allows easy access to the selected row or rows. However, if you are interested in which cell of a table has been clicked, ADF needs some tweaking. This blog is about how to tweak an af:table to get exactly this info. Use Case You like to know which cell in an af:table a user has clicked, e.g. to get some detailed information about the clicked item or cell in the selected row. The sample I show...

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...

We have new tool from Oracle which can help to simplify offline logic implementation for JS apps. In this post I will describe how to use Oracle Offline Persistence Toolkit with Oracle JET. However Offline Persistence is not constrained by JET usage only, this toolkit is available on NPM and can be integrated with other JS solutions. I should emphasise - offline toolkit primary role is to enable mobile hybrid apps to work offline. In my opinion, toolkit usage doesn't stop...

We are excited to announce the open source release on GitHub of the offline-persistence-toolkit for JavaScript client applications, developed by the Oracle JavaScript Extension Toolkit (Oracle JET) team. The Offline Persistence Toolkit is a client-side JavaScript library that provides caching and offline support at the HTTP request layer. This support is transparent to the user and is done through the Fetch API and an XHR adapter. HTTP requests made while the client device is...

Keep an eye open on ADF Task Flow Method Call activities where methods from ADF Bindings are called. JDEV 12c sets deferred refresh for ADF binding iterators related to TF Method Call activities and this causing blind SQL to be executed. Blind SQL - query without bind variables. Let me explain the use case, so that it will be more clear what I'm talking about. Common example - TF initialization method call where data is prepared. Typically this involves VO execution with bind...

As the name implies, a CRUD (Create, Read, Update, Delete) application is supposed to not only access the underlying data, but also to allow the user to perform the entire set of operations to manipulate that data, including create, update, and delete operations. This article illustrates how you can build a CRUD application that supports both data access and data manipulation operations. To build the article sample, you will use Oracle JET, Oracle Database, Oracle REST Data...

Machine learning topic is definitely popular these days. Some get wrong assumptions about it - they think machine could learn by itself and its kind of magic. The truth is - there is no magic, but math behind it. Machine will learn the way math model is defined for learning process. In my opinion, the best solution is a combination of machine learning math and algorithms. Here I could relate to chatbots keeping conversational context - language processing can be done by...

Deploying your JET application in an automated way to your Pi (or other Linux based OS) is pretty easy. First of all; What didn’t work for me was installing jet-cli on my Pi, some dependencies are not available for the ARM-based SoC but luckily there other possibilities! What I will demonstrate here is how you can deploy your JET web application from your development machine straight to your Pi, using only 1 command. I have done this using a Grunt module named grunt-scp which...
