This section lists known issues with Red Hat Decision Manager 7.1.

4.1. Decision Central

Cannot close the standalone editor [RHPAM-976]

Issue: If you make a change in a standalone editor, you cannot close the editor until you save your changes.

Steps to reproduce:

  1. Open a standalone editor.
  2. Make a change to asset.
  3. Try to close the editor.

Expected result: The editor closes.

Actual result: The editor does not close.

Workaround: Save any changes before closing the editor.

In guided rules, guided decision tables, and guided decision templates, the use of the "contains" operator does not add values from enumerations that have quotes. [RHDM-25]

Issue: When enumeration is used for a string field of a fact in guided rules, guided decision tables, and guided decision templates, the resultant rule does not wrap the selected value from the enumeration drop down in quotes ("") and a validation error occurs.

Project cannot be built and deployed in Decision Central when connected to a snapshot Maven repo [RHPAM-1544]

Steps to reproduce:

  1. Start the local Nexus repository.
  2. Install Red Hat JBoss EAP with Decision Central.
  3. Set the value of the kie.maven.settings.custom system property to settings.xml which will point to the Nexus snapshot repository.
  4. Start Red Hat JBoss EAP, log in to Red Hat JBoss EAP, and try to create a project.

Actual result: An error appears.

Workaround: Remove the snapshot Maven repository from the settings.xml file used by Decision Central.

4.2. OpenShift

Opening Case Modeler (legacy) throws a JSON exception [RHPAM-1431]

Steps to reproduce:

  1. Install Red Hat Single Sign-On in OpenShift.
  2. Create a realm.
  3. Install Red Hat Decision Manager in OpenShift.
  4. Open the IT-Orders orders hardware case definition.

Actual result: An error occurs and the application restarts.

Workaround: Replace the keycloak.sh script that is configuring autodeploy:

  1. Download the updated keycloak.sh script from the Business Central Authoring Environment (on Openshift) crashes when a new "Business Processes (legacy)" asset is created article.

  2. Use the script to create a configuration map: 

    $ oc create configmap sso-script --from-file=keycloak.sh=keycloak.sh

  3. Mount the configuration map and override the previous script, where <NAME> is the name of the volume, for example myapp-rhpam: 

    $ oc volume dc/<NAME> --add --type configmap --configmap-name=sso-script --sub-path=keycloak.sh --name=keycloak-script --mount-path=/opt/eap/bin/launch/keycloak.sh

4.3. Decision engine

MVEL expression (1 + 2 * 3 + $v ) causes a "no such method or function " error for bind variable[RHDM-707]

Issue: When using an expression such as (1 + 2 * 3 + $v) in the consequence of a rule which uses the mvel dialect, where $v is a bound variable from rule constraints, the evaluation of the rule produces an exception.

Workaround: Change the expression to (1 + (2 * 3) + $v).
