edgeCore™ 4.3.10 Release Notes

Production date: October 26, 2021

What’s New?


IMAP/POP3 Incoming Email Connection

This release introduces the ability to receive incoming emails. As a result, you are able to access and read your emails in edgeCore.

To configure the email connection, you will need your email client’s IMAP or POP3 Port and Host information. Additionally, depending on your email client’s settings, you may also need to enable IMAP/POP3 access and allow less secure apps to access your account.

We recommend that you use the List visualization to visualize and explore your mailbox.


Micro Charts in Table and List Visualizations

Now you can use micro charts as cell/value renderers in both table and list visualizations to visually represent your data and show trends in a series of values, such as increases or decreases, economic cycles, or to highlight maximum and minimum values.

When you start creating a feed, make sure you feed a string array to the parser (for example “[15,37,5,34,0,9,-11,14,44,-1]”).

The following chart types are supported: Area, Area Spline, Column, Line, and Pie.

An example of a table visualization where a micro pie chart is used:

An example of a list visualization where a micro area spline chart is used:

Moreover, micro charts can also be used in a tooltip action:

New Chart Type: Packed Bubble

When creating charts for smaller datasets, now you can use:

  • packed bubble charts that display data in a cluster of circles
  • split packed bubble charts that are grouped by series to create a hierarchy


Navigate to the Pipeline for a Specific Page

When the admin user is in the Edit page mode, they can easily navigate to and view the pipeline for that particular page by clicking the pipeline icon in the upper-left corner.


Page Variables Improvements

  • Accessing the Manage Page Variables dialog is now done by clicking the pencil icon.
  • Upon hovering over a page variable, the variable will be highlighted and the icons for editing and deleting will be displayed.
  • If you hide a variable, the eye slash icon will be displayed next to the variable’s name.
  • When configuring a visualization action to set the value of page variables, now you can use the Keep Current Value and Reset To Default methods instead of the previously used Unset method.
  • You can now set multiple page variables in custom visualizations, as setPageVars is now exposed in the EdgeCustomWidgetAPI file (install_home\helloworld\node_modules@edge_technologies\custom-widget-api).

RPA Improvements

  • Script Recorder Live Help
    When you start recording new steps, a help icon will appear. Upon clicking the icon, the RPA Help dialog will be displayed, and you can click the toolbar icons/actions to view the help text.
  • Defining a Custom Error Message
    The admin can define a custom error message that will be shown to the end-user if the RPA playback fails. Defining the message is done in the custom/ file.
    The following properties define what type of error dialog is shown to users:
    a) client.rpa.executionFailWarning = true
    This property is set to true by default and will show an error dialog; If you do not want the error dialog to be shown to end-users, set this property to false;

    b) client.rpa.executionFailWarning = custom
    This property shows only the custom message to end-users when there is a playback error;

    c) client.rpa.executionFailWarning = full
    This property shows both the error dialog and custom message;

    The following property is used for the message:
    client.rpa.customErrorDialog = Something went wrong, please contact your administrator.
  • The ability to add dispatchEvent
    Now you can enable dispatching events within the script step configuration.
    The following table contains a list of actions and events that can be dispatched with these actions.

    RPA Action dispatchEvent
    • click
    • dblclick
    • change
    • keyup
    • keydown
    • keypress
    • focus
    • blur
    • input
    • change
    • keyup
    • keydown
    • keypress


Endpoint to Retrieve Content Provisioned to User

To enable you to retrieve the content assigned to a specific user, the following endpoint has been added:
GET /public/users/{username}/content

Response example:

  "/System Menu/User/Logout",
  "/System Menu/System/About",
  "/System Menu/User/Messages",
  "/Content Menu/RPA Registering Users",
  "/System Menu/User/Preferences",
  "/Content Menu/List sparkline",
  "/System Menu/User/Change Password",
  "/Content Menu/gmail list"

Change to Automatic Creation of Pages

The admin is no longer prompted with a dialog upon clicking Save and Close and can now choose when to add a new page by clicking an arrow to access the option to create a new page.

Creating a Connection in Empty Pipeline

When the Pipeline is empty, a message prompts the administrator to create a connection. To make this process easier and faster, now this message is a link to the page where creating connections is done.

Automatic Suggestion to Limit Data

If the number of rows being sent to the visualization exceeds the configured dataset threshold, the admin will be informed about the suggested threshold when in the Edit mode. Additionally, the admin will be able to limit the data by adding a row limit client filter, which will be automatically added to the visualization on their behalf.

The following is a list of visualizations that have a dataset threshold:

  • Chart (Threshold = 2000 rows)
  • Pie Chart (Threshold = 1000 rows)
  • Timeline (Threshold = 500 rows)
  • Heat Map (Threshold = 200 rows)
  • Gauge (Threshold = 5000 rows)
  • Bullet (Threshold = 5000 rows)

Note: If, after some time, you remove the added row limit client filter, you will not be prompted again to add it, that is, you will not be informed about the suggested threshold.

Changing Password over LDAP

LDAP-authenticated users are now able to change their password.


  • generate an SSL certificate on the Active Directory server
  • import the generated certificate into Java’s keystore
  • connect to LDAP over SSL
  • grant the Change Password permission to the user in edgeCore (Provision Roles > Permissions)

Improved Login Error Messages

  • When a non-admin user tries to log into a server that is in maintenance mode, the following message will be displayed: The server is in maintenance mode. Please try again later.
  • If you reach the maximum number of users that your license supports, the following message will be displayed: License limit reached. Please contact your system administrator.

Security Updates

The following libraries have been upgraded:

  • GoJS (version 2.1.49)
  • Apache Tomcat® (version 9.0.54)

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.
  • Errors connecting to 3rd party https webdata/webcontent sources
    edgeCore fails to connect over HTTPS to backend data sources. In this case, one likely solution is to enable SNI. This is a global configuration, so on some systems it might have the opposite effect.
    # — SNI Options; may need to be enabled (ENABLE_SNI=true) when connecting to third-party https webdata/webcontent sources.
  • 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 .
  • Server hard restart requires the license to be reloaded.
