ASSOCIATE WEB DEVELOPER CERT - OUTSYSTEMS - 192QUESTIONS AND ANSWERS|GUARANTEED SUCCESS

What does Outsystems provide? OutSystems Server Development Admin & Ops OutSystems Forge & Community What is the OutSystems server? set of servers that compiles, deploys, manages, runs, and monitors applications the two components of development integration studio & service studio two components of admin and ops service center & lifetime service studio low-code visual development environment that enables developers to rapidly create amazing mobile and web applications integration studio dev environment for integrating external resources; integrate existing data and code as well as create .NET code extensions service center platform server management console; admin console that is accessible via browser; access to platform server configuration for admin and operations teams lifetime web app that manages lifecycle across environments; extends service center's capabilities to cross environment scenarios; complete application lifecycle management via browser outsystems forge source of downloadable components to help speed app delivery what are screen actions bound to? widgets on a screen where can server actions be called? in any flow how many input and output parameters and local variables can server actions have? multiple do screen actions have output parameters no do preparations have parameters or variables no server actions that are set as a function are... 1. restricted to one output parameter 2. available in expressions what is an action flow where a piece of logic is defined actions flows can have one of what and multiple of what one start node multiple end nodes and raise exceptions what can screen actions and preparations also end with (2 things) besides end and raise exception? destination nodes and download can a flow have multiple exception handlers? yes, but action and exception flows cannot intersect what does that assign statement do? allows setting values to variables or parameters how are values assigned in assign statements? top to bottom and changes occur immediately what are some accelerators that service studio provides regarding assign statements? auto-assign of remaining attributes standard type-matching values suggestion what does an if statement do? creates a conditional branch in an action flow what does a switch statement do? creates conditional branching with multiple branches how does the switch statement operate? conditions are evaluated from first to last only the first branch that evaluates to True is executed or the otherwise branch and the otherwise branch is mandatory what does a for each statement do? allows iterating through a record list how does a for each statement operate? the cycle branch is followed for each record in the list -branch must return to the for each so the loop can continue -branch can create other conditional/alternative branches the branch is followed after the cycle completes what does RecordList.Current get in a for each statement the current record being iterated within the loop how to implement an ad-hoc loop use the if to evaluate a loop condition -follow a cyclic branch when condition is true -exit the loop when condition is false in the cyclic branch of an ad hoc loop... branch must return to the if to continue the loop branch can create other conditional/alternative branches when is an exception used in a screen action? when an operation fails unexpectedly at runtime the execution is moved to an exception handler flow what kind of exception handler flows can an action have? database exception security exceptions custom user exceptions how can an exception be raised? automatically raise exception statement what happens when an exception is raised? execution is moved to the handler most specific to the exception thrown execution continues through that handler flow how does a global exception handler get called? if a handler doesn't exist in the current execution context, the server bubbles-up to check any outer contexts until a matching handler is found details about the module global exception handler located in the common flow 1 per module at most highest possible level to bubble-up should handle all exceptions!!! validating user inputs help... limit user mistakes what are some reasons that input fields would need validated input fields may.. have different data types depend on other user input values require business specific validations does outsystems provide mechanisms to help implement input validations? yes T or F: outsystems provides build-in validations for input widgets T what are 2 of the built-in validations mandatory fields must be filled data type in must comply with the data type of the variables bound to the widgets how and when are validations performed? automatically when data is submitted to the server what widgets do not have validations? link/button widgets with the navigate method what does the validation property do on a widget? influences how the input validation will be performed? what are the 3 types of validations on a link or button? server, client & server, none what happens in a server validation? inputs are submitted to the server what are each input field's two runtime properties? valid: boolean property validationMessage: text property -displayed in the case that input is not valid when built-in validations are performed automatically.... valid property is auto set to false but it still needs to be explicitly checked in the action flow what is a custom server-side validation? when a developer writes their own validations -must be perform in the action flow if the form input fields are invalid... you should set the valid property to false and set the ValidationMessage accordingly when should the form valid property be checked? after all custom validations what if one input is invalid? the form is automatically not valid can the form valid property be explicitly assigned? No are built-in validations checked on the server or client side? client if client side validations are valid then what happens? Invalid? inputs are submitted to the server user gets error message immediately how do server side validations work? as the server validation method custom server-side validations can be defined how does the none validation work? inputs are submitted to the server no built-in validations are performed on client or server side custom server-side validations can be defined
