OpenL Tablets 5.0.5 is a major feature release introducing the repository, a new table editor, and the Business Expression Language.

New Features

JCR-Based Repository

A content repository based on the Java Content Repository (JCR) standard is now available for storing and versioning OpenL rules projects.

AJAX-Based Table Editor

A new browser-based table editor uses AJAX for interactive cell editing of Excel tables directly in WebStudio.

Vocabulary

Vocabulary support is introduced, enabling business-friendly naming and language customization for rules and properties.

Business Expression Language (BEX)

The Business Expression Language (BEX) provides a more natural, Excel-like syntax for writing rule expressions in OpenL Tablets.

Java Proxy for OpenL Module Wrapping

OpenL modules can now be wrapped using a Java Proxy, providing a clean interface for invoking rules from Java code.

Bug Fixes

  • Fixed: OpenLWrapper used in a multi-threaded environment — a local copy of RuntimeEnv is now created per thread.
  • Fixed: Added operators to handle long arithmetic correctly.
