When building Oracle JET Model/Collection structure to render table, you should be careful defining ID attribute. This attribute must have unique values only, if there will be duplicates in ID, then table rows will be rendered incorrectly. Take as example below structure for Employees REST endpoint. EmployeId attribute provides unique values and it should be defined as ID for JET model: Let's try and see what happens when non-unique DepartmentId attribute is set for a key in...

In a previous blog we described how to retrieving the masterdata from a VBCS Business Object. In this blog we will expand this further with a validity period for the masterdata Now let’s expand our scenario (see previous blog)  a little further. Currently, one of the means of transport in the Decision model is a bike. Many bikes in the Netherlands are currently being replaced by an electrically powered version. Jarvis Pizzeria will also replace regular bikes with electric...

In this blog we describe a way to store the Input and Output of Decision Model Invokes (in JSON format). From an administrative point of view, we at Jarvis believe it is important that we can always see how we have achieved certain results. In this case this means that we want to know with which variables the Decision Model was invoked and what the outcomes were. How we do this is subject of this blog. Saving the results is e.g. possible after performing the ‘Calculate Delivery...

  Visual Builder allows you to create applications that can continue to function even when your device is disconnected from the network. To do that Visual Builder leverages the Oracle JET offline persistence toolkit. This toolkit enables your application to cache data on the client and serves it back from the cache when you are issuing the same REST call but your device doesn't have access to the server. It also allows you to "execute" operations such as adding records while...

The API Platform when you configure IDCS to provide the option to authenticate users against a corporate Identity Provider such as Active Directory will automatically update the Management Portal Login screen accordingly. However today it doesn’t automatically update the Developer Portal login page.  Whilst perhaps an oversight, it is very easy to fix manually when you know how. As result you can have a login that looks like: The rest of this blog will show what’s needed to...

We are using Pay As You Go Oracle VBCS instance and had an issue with accessing VBCS home page after starting the service. The service was started successfully, without errors. But when accessing VBCS home page URL - "Error 404--Not Found" was returned. I raised a support ticket and must say - received the response and help promptly. If you would encounter similar issue yourself, hopefully, this post will share some light.Apparently "Error 404--Not Found" was returned,...

  One of the key ways to make your application drive better user results is to use charts. Chart makes it easier for users to turn raw data into useful information. As they say "A picture is worth a thousands words". Oracle Visual Builder's quick starts makes it very simple to create basic charts leveraging the data visualization components of Oracle JET. But if you require more complex charts and if you want to improve the performance of your application, you might want to go...

There are circumstances in which notifications from the Oracle API Platform CS could be seen as desirable.  For example, if you wish to ensure that the developers are defining good APIs and not accidentally implementing APIs that hit the OWASP Top 10 for APIs. Then you will probably configure things such that developer users can design the APIs, configure the policies, but only request an API to be deployed. However, presently notifications through mechanisms such as email or...
