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
Inputs
Label | Name | Type | Mandatory
-----------------------------------------
Message | message | String | Yes
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
Inputs
Label | Name | Type | Mandatory
---------------------------------------------------
03_sys_id | 03_sys_id | String | Yes
04_err_message | 04_err_message | String | Yes
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
Created : 2020-10-07 00:07:53
Name : jw_1006_Subflow_01
State : Complete
Runtime : 3
Created by : admin
Sys Id : 2725e33b316fd81075d1d5914dca84df
Open in Operations View
Subflow Input
VARIABLE NAME | TYPE | RUNTIME VALUE
------------------------------------------------------------
03_sys_id | String | 59f4eff71b6fd810811c520d0a4bcb5a
04_err_message | String | Test Message From jw_TestBR02
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
