Tom Sawyer Perspectives, Java Edition

Releases

Release 13.0.0

DateMay 22, 2024
StatusGeneral

Overview

This release features a native React-based web client framework for table, tree, and inspector views, toolbars, dialogs, context menus, as well as the Web Previewer. In addition, this framework includes updated styles for view components, tabs, toolbars, and dialogs, bringing a modern look and feel to Perspectives applications. The Generate Web Application Code feature supports the creation of React web applications using the new React-based view components. This feature also improves support for application deployment to the Tom Sawyer Perspectives Deployment Container on AWS Marketplace with automatically generated deployment instructions and CloudFormation templates.

The Query Builder and Load Neighbors features add support for advanced graph pattern searches without the need for knowledge of the Gremlin or Cypher query languages. Commit capability has been added to the RDF integrator. Improvements to the expansion of nested drawings provide better layouts. The new Augmented Centrality algorithm allows you to calculate centrality values for nodes and edges at the same time through a combination of different centrality techniques. Support for Disjoint Paths, Sorted Paths, and a function to return the most recently executed analysis algorithm have been added to the Designer. Accelerated performance across Designer, Web Previewer, and Perspectives applications ensure faster load times, and a more responsive interface. Model-Based Engineering now has the capability to navigate through diagrams directly.

Perspectives has been upgraded to Spring Framework 6.1.6 and Spring Boot 3.2.5, and is now compiled with Java 17. Also, many third-party libraries have been updated to eliminate potential vulnerabilities.

Fixes

Integrators

  • Fixed schema extraction to correctly set the wildcard element type, Base Vertex, as the source and target element type for edges, instead of overly specific types
  • Fixed data loading issue when querying a date attribute using Query Builder

Model

  • Fixed the functionality of TSModelIndex.getModelElements to ensure accurate retrieval of elements based on date queries

Views

  • Drawing
    • Fixed the occurrence of an infinite loop within TSShapeUIElementGWTCanvasRenderer when the Refresh interval was set
    • Fixed the issue where Drawing View data was erroneously transmitted in the middle of Rule Sheet Execution

Installers

  • Fixed a bug when using the Windows Installer in silent mode

Issues

  • There is an issue using the default configuration for the HTTPS protocol with the Neo4j integrator. Contact Support for assistance in using this configuration.
  • The Generate Schema Code feature, with support for JPA (Java Persistence API), requires Hibernate version 6.5.1 to properly execute.
  • Some options in the Export Image dialog in modern web client do not function.
  • The Sign Out action in modern web client has an issue.
  • You may see warnings of "Application Context Not Available" and "Failed to Find View" in the console on Designer starts. Please ignore.
  • You may see a warning of "Unknown Publisher" while using the uninstaller on Windows 11. Please ignore.
  • The macOS and Linux installers bundle with a JDK targeting x64 CPUs. To achieve improved performance on a device with an Aarch64 CPU (such as the M1 and M2 CPUs on new Mac Minis and Mac Pros) you can install a JDK targeting Aarch64 and run against that.
