Release Notes 5.8

New Features

  • Web Services Application rewritten

    OpenL Web Services application supports complex deployments with advanced functionality. Many scenarios are covered just using configuration. Customization points are available for complicated deployment scenarios. By default behavior is the same to previous version of the application.

  • Simplified OpenL tools configuration

    Configuration files for all OpenL Tablets tools such as Webstudio, Rules repository, Web Services application were revised and simplified. WebStudio contains UI for some properties editing. Changed properties will be stored in 'webstudio.home' directory to simplify application upgrade.

  • Expression indexing in arrays

    New syntax is introduced to allow choosing one (array[select first having <condition>]) or several elements (array[select all having <condition>]) from array matching some boolean condition. Conditions are written the same way as in “if” or condition column of DT.

  • New utility methods

    New utility methods are available anywhere in rules: max, min, avg, big, small, median, sum, product, quotient, mod, allTrue, anyTrue, xor, slice, sort, contains, indexOf, out (out function extended to support all types)
