Rapid Application Development with OutSystems

By: Ricardo Pereira

Overview of this book

OutSystems is a software development platform that speeds up the build phase by abstracting code and making almost everything visual. This means replacing textual language with visual artifacts that avoid lexical errors and speed up code composition using accelerators and predefined templates. The book begins by walking you through the fundamentals of the technology, along with a general overview of end-to-end web and mobile software development. You'll learn how to configure your personal area in the cloud and use the OutSystems IDE to connect with it. The book then shows you how to build a web application based on the best architectural and developmental practices in the market, and takes the same approach for the mobile paradigm. As you advance, you'll find out how to develop the same application, and the great potential of reusing code from one paradigm in another and the symbiosis between them is showcased.The only application that'll differ from the application in the exercise is the one used in business process technology (BPT), with a focus on a common market use case. By the end of this OutSystems book, you'll be able to develop enterprise-level applications on the web and mobile, integrating them with third parties and other systems on the market. You'll also understand the concepts of performance, security, and software construction and be able to apply them effectively.

Exercise 6 – creating Client Actions and using them on the frontend

In this exercise, we will continue the application that has been developed in the previous exercises. Let's create a client action that allows us to change the state of a ticket to Closed and use it on the ticket listing page, making it available for each of the tickets that are not yet in that state. Proceed as follows:

  1. Select the Logic tab, right-click on the Client Actions folder, and select Add client action. Name it Ticket_Close, as illustrated in the following screenshot:

  1. Now, let's create an input variable of type TicketId, as illustrated in the following screenshot:
