This use case specifically useful for ADF UI value change listener. If there is business logic to be invoked when field value is changed, we can can call ADF BC custom method from assigned value change listener. However new value is not yet propagated down to ADF BC model - we would need to pass it as parameter to custom method. What if want to have new value to be available in ADF BC model without passing new value from value change listener as parameter? This is possible if...

  Your starting point should be the What's New doc for PCS 16.3.5. Click here to read it. One of the most interesting additions is the new web forms functionality. Let's be honest, the previous Frevvo based forms were rather basic, they've even been renamed Basic Forms. So now you have the choice, you take either the basic forms - very effective for eGov style forms based apps - or else the new web forms with their richer UI. So let's take a look. Web Forms From the docs -This...

This post is about ADF BC LOV. I will describe how you could optimize bulk insert of new rows into VO, when some of the attributes are assigned with LOVs. By default ADF would validate new row attribute value through LOV (LOV Validation and Programmatic Row Insert Performance) for each new row. This will lead to bad performance, especially if you insert a set of new rows programmatically - there will be multiple SQL queries executed to check if LOV attribute value exists.My...

The focus is once again on business analysts and other non-technical people to automate business processes. Oracle has keyed them “citizen developers”.

Some of you who would try to implement custom method with ADF BC REST may face JDeveloper 12.2.1.2 wizard issue. JDeveloper 12.2.1.2 wizard is refusing to register ADF BC REST custom method, but it works perfectly on ADF runtime. Seems to be JDeveloper 12.2.1.1 - 12.2.1.2 bug. There is a workaround to modify REST service configuration manually and include custom method binding. Sample application (available on GitHub - jetcrud). This sample implements custom method in VO...

  The trifecta of IoT, Cloud and Analytics have been transforming many aspects of our lives and business. Cities, healthcare, transportation, farming, fitness, home, manufacturing and utilities have been the key beneficiaries of this fast-emerging paradigm. While consumer devices like Fitbit and Amazon Alexa get lot of attention from the media, the commercial buildings have been quietly turning into Software Defined Buildings (SDB). By doing so they are not only lowering the...

I learned a few interesting things from my colleague Sylvain Côme in London today. Sylvain is a very big enthusiast of Oracle JET and is introducing it in a variety of contexts. For wireframing, he uses Adobe XD. For the images in his wireframes, he has installed SVG Crowbar into his Chrome browser, which enables him to download SVG files of images in the Oracle JET Cookbook. He then imports those SVG files into his wireframe in Adobe XD, where he can even edit them,...
