Abstract

This document contains release notes for Red Hat Process Automation Manager 7.8.

Preface

These release notes list new features, features in technology preview, known issues, and issues fixed in Red Hat Process Automation Manager 7.8.

Chapter 1. Product overview

Red Hat Process Automation Manager is an open-source business automation platform that combines business process management (BPM), case management, business rules management, and resource planning. It enables business and IT users to create, manage, validate, and deploy business processes, cases, and business rules.

Red Hat Process Automation Manager uses a centralized repository where all resources are stored. This ensures consistency, transparency, and the ability to audit across the business. Business users can modify business logic and business processes without requiring assistance from IT personnel.

Red Hat Process Automation Manager 7.8 provides increased stability, several fixed issues, and new features.

Red Hat Process Automation Manager is fully supported on Red Hat OpenShift Container Platform and can be installed on various platforms.

Note

Red Hat Process Automation Manager requires Java 8 or later.

For information about the support policy for Red Hat Process Automation Manager, see the Release maintenance plan for Red Hat Decision Manager 7.x and Red Hat Process Automation Manager 7.x.

Chapter 6. Known issues in Red Hat Process Automation Manager 7.8.0

This section lists known issues with Red Hat Process Automation Manager 7.8.

6.1. Business Central

An error message about missing KIE Server configuration on dashbuilder runtime must be improved [RHPAM-3058]

Issue: The dashbuilder runtime user interface currently displaying a wrong error message about missing KIE Server configuration.

Steps to reproduce:

  1. Start Business Central.
  2. Try to import the KIE Server dataset on dashbuilder runtime.

Expected result: The dashbuilder runtime displays an error message with missing or wrong KIE Server system property.

Actual result: The dashbuilder runtime is not displaying an error message with missing or wrong KIE Server system property.

Workaround: None.

The dodeploy file is not available in the dashbuilder runtime distribution [RHPAM-3031]

Issue: The dashbuilder runtime application comes as a zip folder, containing all the files that are required for the deployment. The zip folder contains a dashbuilder-runtime.war file, but the dashbuilder-runtime.war.dodeploy file is not available in the folder.

Workaround: Update zip folder by adding dashbuilder-runtime.war.dodeploy file as a copy of the folder dashbuilder-runtime.war. Alternatively, the distribution must be a war file and you can directly copy to the deployments folder.

When you export the dashbuilder related data, gradual export displays internal data sources [RHPAM-3021]

Issue: When you export the dashbuilder related data, gradual export displays internal data sources for user selection. It should display the public data sets only.

Workaround: None.

In guided decision table, the verifier feature does not work properly for columns with the Date data type [RHDM-1399]

Issue: In a guided decision table, the verifier feature displays an error when you open a table that contains a specific combination of template keys in the actions column. These template keys are associated with the Date data type.

Workaround: None.

Issue: You cannot select the data cell of a guided decision table with the help of a mouse.

Steps to reproduce:

  1. In Business Central, go to Menu → Design → Projects and click Mortgages.
  2. Open the Pricing loans guided decision table.
  3. Click the data cell of the guided decision table.

Expected result: You can select the data cell of the guided decision table with the help of a mouse.

Actual result: You cannot select the data cell of the guided decision table with the help of a mouse.

Workaround: You can select the header cell using mouse and then navigate into the data cells with help of keyboard arrow keys.

You cannot use undo and redo keyboard shortcut keys in the grid editor [RHDM-1397]

Issue: You cannot perform undo (Ctrl+Z) or redo (Ctrl+Shift+Z) operation in the grid editor with the help of keyboard shortcut keys.

Steps to reproduce:

  3. Press (Ctrl+Z).

    One decision node is removed.

  4. Navigate to the grid editor of the remaining node.
  5. Add some context entries.
  6. Press (Ctrl+Z).

    The same context is present.

Expected result: You can use undo and redo keyboard shortcut keys in the grid editor.

Actual result: You cannot use undo and redo keyboard shortcut keys in the grid editor.

Workaround: The Undo button from toolbar works correctly.

You cannot convert the rule names from guided decision table into a spreadsheet decision table [RHDM-1396]

Issue: You cannot convert the rule names from a guided decision table into spreadsheet decision table (XLS).

Steps to reproduce:

  1. In Business Central, go to Menu → Design → Projects and click Mortgages.

  7. Open the generated XLS file, click Source tab, and verify the rule names.

Expected result: Custom rule names are correctly converted from guided decision table into spreadsheet decision table (XLS).

Actual result: Custom rule names are not correctly converted from guided decision table into spreadsheet decision table (XLS).

Workaround: None.

The performance for DMN-based test scenario is degraded when the tested DMN model includes a PMML model [RHDM-1415]

Issue: When you create a test scenario for a DMN model which includes a PMML model, the validation and creation of a test scenario takes time and the performance is degraded.

Steps to reproduce:

  1. Import a project in Business Central.
  2. Create a DMN-based test scenario including DMN model, which contains PMML model.
  3. Click OK.

    Tests run slow and test scenario takes too much time to validate.

Workaround: None

When you try to invoke a Business Knowledge Model (BKM) function from included DMN model, the validation fails [RHDM-1395]

Issue: You can not call the BKM function imported from another DMN model, which is aliased with the name containing . characters. If you try to invoke BKM function, the validation fails.

Steps to reproduce:

  1. Create an empty Salary.dmn DMN model.
  2. Create an another empty WorkingHours.dmn DMN model.
  3. Import WorkingHours.dmn DMN model into Salary.dmn DMN model.

Workaround: None.

Business Central pod fails to start when known_host file is missing from the Git hook secret [RHPAM-3056]

Issue: The Business Central pod fails to start and remains stuck at Container Creating status if the known_host file is missing from the Git hook secret.

Steps to reproduce:

  1. Create the following post-commit script.

    cat post-commit
    #!/usr/bin/sh
    echo "running post-commit git hook"
    git clone git@github.com:Sgitario/kjar-examples.git
  2. Upload this post-commit file into the Openshift.

    oc create configmap githook-post-commit --from-file=post-commit=post-commit
  3. Create the Git hook secret.

    oc create secret generic githook-ssh-key-secret --from-file=id_rsa=/mypath/.ssh/id_rsa

Expected result: Business Central pod does not fail even after the Git hook secret is missing some configurations.

Actual result: Business Central pod fails to start and remains stuck at Container Creating status.

Workaround: Specify the following known_host file and create the Git hook secret again.

oc create secret generic githook-ssh-key-secret --from-file=id_rsa=test_manual/.ssh/id_rsa --from-file=known_hosts=test_manual/.ssh/known_hosts

Steps to reproduce:

  1. Run Red Hat Process Automation Manager installer with the default options.
  2. Use Red Hat JBoss EAP as an installation container.
  3. Complete the installation, generate an installation script, and name it as auto.xml.
  4. Clean the used Red Hat JBoss EAP container and run the installation again using the generated installation script:

    java -jar rhpam-installer-7.8.x.jar auto.xml -variables rhpam.username=rhbaUser,rhpam.password=bpmsAdmin123$
  5. Run the installed Red Hat Process Automation Manager.

Expected result: Red Hat Process Automation Manager installer is not trying setup any Red Hat JBoss Web Server related properties and installation on Red Hat JBoss EAP using automated script succeeds.

Actual result: Red Hat Process Automation Manager installer tries to setup Red Hat JBoss Web Server related properties and installation on Red Hat JBoss EAP using automated script fails.

Workaround: Install manually. Do not use the generated script for Red Hat JBoss EAP.
