  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?

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 when is the valid property of the input widget checked? when rendering if the valid property is set to false... regular widget is displayed specific styling is applied (red border) displays the validation message when the input gains focus troubleshooting is generally a combination of 2 things debugging and monitoring what does debugging do? suspends code execution at given points analyzes the value of variables developer can execute code step by step what is monitoring? analyzing and correlating system logs outsystems records events in logs like errors, slow queries, etc. how does debugging work in service studio?

allows you to place breakpoints on elements that generate code such as action/preparation statements and screen widgets when should you start the debugger? before opening the app in the browser what does service studio do when debugging? registers the breakpoints and connects to server to stop execution where are breakpoints listed? in the debug panel *note that they can be temporarily disabled or removed what commands are available once code execution stops at a breakpoint?

  • stop, continue, suspend, abort
  • step over, step into, step out what does the break on all exceptions button do? forces the debugger to suspend the execution of threads when exceptions occur handled or unhandled when do you inspect the values of variables in debugging? when code execution is stopped T/F watches are always displayed, even if out of scope T what do breakpoints do? stop execution of requests made to that module directly why debug in the personal area? no impact to the main version of the application faster re-publication after changes does not create a new version of the module with every publish what is monitoring act of analyzing and correlating logs what does ajax do allows web pages to change content dynamically aka no need to refresh the whole page how does ajax work? sends small asynchronous requests to the server the end user can still continue to interact with the screen what is the 1 main reason to use ajax end-user experience is greatly improved how to get ajax in a screen action to work set the link or buttons method to ajax submit and set the destination to a screen action what does the response of ajax refresh contain only the refreshed screen content this is available for named widgets only what happens when multiple ajax refreshes are called in the same screen action they will be executed in order what if an ajax refresh is called in a screen action but the method calling the action isn't ajax submit? the ajax refresh is ignored what does "refresh data" do?
