Message by addErrorMessage() is not displayed when using Subflow from Business rule - Known Error

Message by addErrorMessage() is not displayed when using Subflow from Business rule Description Customer define Flow action using addErrorMessage() in Paris to display custom error message.

========================= Process Automation > Flow Designer > New > Action Name : jw_1006_AddErrorMsg

Script -------------- (function execute(inputs, outputs) { gs.addErrorMessage(inputs.message); })(inputs, outputs); -------------- =========================

When customer call this FD action from business rule directly, custom error message is displayed as expected. However, when they call this FD action from BR via subflow, custom error message is not displayed.

Steps to Reproduce

1.Create Flow Action using addErrorMessage(), then publish Process Automation > Flow Designer > New > Action

Name : jw_1006_AddErrorMsg Accessible From : All application scopes Application : Global

Script step Input Variables Name | Value ----------------------------- message | action > Message

Script -------------- (function execute(inputs, outputs) { // ... code ... gs.addErrorMessage(inputs.message); })(inputs, outputs); --------------

2.Create Business Rule to call FD Action System Definition > Business Rules

Name : jw_TestBR01 Table : Incident Active : Yes Advanced : Yes

When to run When : before Order : 10 Insert : Yes Update : Yes Filter Condition Short description contains TestBR01

Advanced Condition : (null) Script ---------------------- (function executeRule(current, previous /*null when async*/ ) { var inputs = {}; inputs['message'] = gs.getMessage('Test Message From jw_TestBR01'); // String sn_fd.FlowAPI.executeAction('global.jw_1006_AddErrorMsg', inputs);

current.setAbortAction(true); current.setWorkflow(false); })(current, previous); ----------------------

3.Test to create a incident Incident > Create New Number : INC0010002 Short description : TestBR01 Save ==> Test Message From jw_TestBR01 Invalid insert

The custom error message is displayed with "Invalid insert" as expected. BR:jw_TestBR01 and FD Action:jw_1006_AddErrorMsg works normally.

4.Create Subflow to call FD Action Process Automation > Flow Designer > New > Subflow

Name : jw_1006_Subflow_01 Application : Global Accessible From : This application scope only Run As : User who initiates session

Outputs Label | Name | Type ------------------------- result | result | String

Actions 1:jw_1006_AddErrorMsg Action : jw_1006_AddErrorMsg Message : Input > 04_err_message

2:Assign Subflow Outputs Name | Data ---------------- result | NG

5.Create Business Rule to call Subflow System Definition > Business Rules

Name : jw_TestBR02 Table : Incident Active : Yes Advanced : Yes

When to run When : before Order : 11 Insert : Yes Update : Yes Filter Condition Short description contains TestBR02

Advanced Condition : (null) Script ---------------------- (function executeRule(current, previous /*null when async*/ ) {

var inputs = {}; var sys_id_03 = current.sys_id;

inputs['03_sys_id'] = sys_id_03; // String inputs['04_err_message'] = gs.getMessage('Test Message From jw_TestBR02'); // String

var result = sn_fd.FlowAPI.getRunner().subflow('global.jw_1006_Subflow_01').inForeground().withInputs(inputs).run(); var outputs = result.getOutputs();

var answer =outputs['result'];

if(answer === 'NG'){ current.setAbortAction(true); current.setWorkflow(false); }

})(current, previous); ----------------------

6.Test to create a incident Incident > Create New Number : INC0010003 (Sys ID:59f4eff71b6fd810811c520d0a4bcb5a) Short description : TestBR02 Save ==> Invalid insert

The custom error message is NOT displayed, only "Invalid insert".

7.Check Flow engine context Process Automation > Flow Administration > Today's Execution

Open in Operations View

Subflow Output VARIABLE NAME | TYPE | RUNTIME VALUE ---------------------------------------- result | String | NG

==> Subflow set inputs correctly, but custom error message is not displayed In this situation, FD Action:jw_1006_AddErrorMsg does not work as expected.

Workaround Create a subflow output with the message to be displayed or status code.

Pass this output back to the calling business rule who should really display the message anyway
