Release Notes

v5.22.0.1 on the GitHub

New Features

Use streaming read for xls and xlsx files

OpenL switches to use an Event API to process xls and xlxs files while in read-only mode. Consequently, WebStudio and WebServices consume much less memory when only reading xls/xlsx files. During Editing DOM read approach is still used

Functionality to use object binding in logging interceptors

Functionality supports converting of SpreadsheetResult before saving into storage

Ability to store description of Conditions, Returns and Actions in a separate table

Conditions, Actions and Returns now can be managed in separate tables and then used in SmartRules tables

 

Improvements

Core, Demo:

  • Java 11 Support

Core:

  • Support StringRange in Rules
  • Support DateRange in Rules
  • Ability to use $RuleId/$Rule in Rules and SmartRules
  • Refactoring of OpenL Message to eliminate ThreadLocal usage
  • Keyword "RETURN" is optional for Spreadsheet tables that returns a particular type
  • Created a new property "calculateAllCells" for Spreadsheet type table that returns a particular type
  • Ability to use SPI for loading implementation of ResolvingStrategy instead of Spring Framework
  • Added a new function that receives Startdate, Enddate and returns fractional interval between it. The behavior is similar to native excel function DATEDIFF and has the same arguments. Example: dateDif(startDate, endDate, "D"), where "D" means difference in days

Webstudio:

  • Added a hint for the types of SpreadsheetResult fields
  • Added a the ability to save input data of executed test cases in Excel
