edgeCore™ 4.4.1 Release Notes

Production date: April 01, 2022


This release uses Java 11, so you need to upgrade to this version of Java in order to be able to run edgeCore™ 4.4.1.
Notable changes related to proxy rules and JavaScript transforms are as follows:

  • .getBytes() is not a function ;
  • There is no longer a getter specially added for strings, so .length() for strings must be .length ;
  • Any other function name that clashes with an existing JavaScript property on an object will also have this issue as .length():
    – .startsWith()
    – .indexOf()
    – .match()


What’s New?


Advanced Mode Added

To help you further customize charts, the advanced settings mode has been added. Once the mode is enabled, you will be able to provide HighCharts JSON configuration and also run JavaScript ( ${…javascript…}$ ).
When running JavaScript, the following is available:

  • rows: array of objects that is the dataset;
  • columnData(columnId): an array of values that represent the values in that column of data;
  • moment: moment.js object for date/time conversions;

3D Charts

When configuring a chart visualization, you are now able to show the chart in 3D to get an interesting visual effect. In addition, you can rotate the 3D chart to inspect points from different angles by dragging the chart with the mouse.

NOTE: Line and spline chart types cannot be shown in 3D.


Restoring and Exporting Configuration of Pipeline Nodes

Now you can export and restore configuration of any pipeline node as a JSON file.

Showing Used Node Variables in the Pipeline

  • You can expand node variables by clicking the arrow next to the number of variables;
  • Node variables can be expanded by enabling the Show Node Variables toggle in Pipeline Settings (accessed by clicking the gear icon in the pipeline);


Command Line Interface

Creating Directories via CLI

To create a directory on the server via CLI, now you can run the following:
./ files –mkdirs -p /data/DirectoryName –user admin –pass admin

For example, we have created a directory whose name is test_directory:

Command Center

Server Logs and System Info Added

System Info and Server Logs are now also available in the Command Center.



Chart Visualization Improvements

  • You can now choose between three series types: mixed, dynamic, and single;
  • When mixed series is selected, the first attribute requires chart type override;
  • When single is selected, the override field is disabled;
  • If pie is the default type, you can choose between single and dynamic series;
  • If bubble is selected in override, you will need to define a radius in the bubble renderer;

Gauge Visualization Improvements

  • The option to disable animation has been added.
  • Now you can have a dual-color gauge and also define a threshold value.


Page Filtered Views Added to Recent

When you filter the pipeline by pages, those pages will be listed in the Recent dropdown.

Properties Unified in Server Config

To improve the experience for the admin, Server Config UI (system menu > System > Admin Tools > System Config) has been updated to have only GLOBAL scoped items.

Displaying Stacked Visualizations as Tabs

By default, stacked visualizations are displayed in a drop-down menu. Now you can view them as tabs, too. To do so, you will need to enable the Display Stacked Widgets as Tabs toggle switch in Options.

Additional Pipeline Settings

The following options have been added to pipeline settings:

  • In Link Style, Straight has been added as the default style for node links (as seen in the screenshots below);
  • Spread Links
    – when enabled, the starting point for each node link/line is different (each node has its own starting point);

    – when disabled, links/lines start from the same place;
  • Show Node Variables
    – when enabled, used node variables are expanded in the pipeline (as seen in the screenshots above);

Opening Unread Messages with a Single Click

If there are unread messages, upon hovering over the number and clicking on it, you can access the Message Center.

Size Column Added to Backup & Restore

The Size column has been added to the Backup & Restore page. As a result, both Backups and Recovery tabs can be sorted by size. Moreover, when the Recovery directory becomes larger than 5GB, a message will be displayed to notify the admin.

Set All Values as Default Option Added to Page Variables

When you change the values of page variables, you can set all those values as default with a single click – you just need to click the gear icon next to the pencil icon.

RPA Improvements

  • Now you can disable any step in the script, which is useful for testing different versions of the steps.
  • You are able to use a server action response within the RPA script as a scriptVar.
  • A help button containing more information and examples on custom JavaScript Eval functions and their results has been added to the Edit JavaScript Expression dialog.
  • The Initialize & Test button has been added to the Edit JavaScript Expression dialog. Use the button to initialize the element, that is, run the script up to that step, and then test.
  • A function has been added to JavaScript Eval enabling you to set a page variable to any value.

H2 Database Version Upgrade

The H2 database has been upgraded to version 2.1.210.

Angular Version Upgrade

Angular has been upgraded to version 13.

Known Issues

  • Cache Compatibility (MySql / H2 / Oracle / Microsoft SQL Server)
    edgeCore supports using H2 by default, but the system can be switched to use a MySQL Database, Oracle Database, or Microsoft SQL Server as the CacheDB. If an export is restored, any SQL Transforms should be reviewed, as H2 specific query syntax will need to be converted to MySQL, Oracle, or SQL Server syntax. There is a script utility that reports some of these issues, and the script itself can be extended to report which Transforms reference syntax that requires updates.
  • Custom Login Page Compatibility
    Login pages built on versions prior to edgeCore v4.1 are not compatible. An upgrade script is included to help stash custom login pages into ‘static-web/login-pre4.1’ and the customizations will require manual migration to the new default template.
  • HTML Template Visualizations
    Based on the version you are upgrading from, the following issues could cause you to need a rewrite to your HTML Template Widgets:
    – Due to the significant upgrade to Bootstrap 4, Glyphicons are no longer included. If you have custom HTML Templates that use them, in v3.11 they will all be empty.
    – Due to the upgrade to Angular 9, HTML Templates that used AngularJS 1.x syntax will have to be rewritten.
  • Common Table Expression ‘WITH’ Clauses
    edgeCore uses the H2 database in support of the SQL Transforms. SQL that uses Common Table Expression (CTE) ‘WITH’ clauses have been identified as causing two issues.
    – Lock Timeouts: Transforms fail to run as temporary tables fail to be cleaned up.
    – Memory Leaks: The temporary table results are not being cleaned up properly in all instances, and it will trigger Out Of Memory on the JVM.
  • Issues with using Auth/Cache DB with MySQL 5.7 (MariaDB 10.1.x – 10.3.x)
  • Cluster configuration fails to render LDAP domains on content instances after restore on primary admin instance.
  • Cluster configuration restore may require existing nodes to be removed and re-registered after a full restore.
  • If you are having issues with icons loading in edge, enable headless Java by adding CUSTOM_JAVA_OPTS=-Djava.awt.headless=true in environment.bat/.sh .
