Hi masters,
I have a subflow which has few UDPs. In the main flow, I have to override the current UDP values before the message reaches the subflow. I put a Compute node on my flow right before the subflow, and tried to set these values using ESQL, but those UDP variables does not appear in the message tree.
The knowledge center shows to do it in Java using setUserDefinedProperty() method, but I wouldn't like to use a JCN nor Java classes.

Presumably you mean you need to set them to different values for each message that passes through, rather than to a single value that is different from the default when you deploy.
User Defined properties are accessed in ESQL through EXTERNAL variables.

Hi mqjeff,
I am able to access it, but not to change it. I tried to set a new value, but I got the following error:
Value of constant "address" cannot be changed.
My ESQL piece of code:
CREATE COMPUTE MODULE MAIN_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
-- CALL CopyMessageHeaders();
-- CALL CopyEntireMessage();
SET address = 'TEST';
RETURN TRUE;
END;
END MODULE; |

Given your description of what you want to do, you might try a variable in the environment tree.
You can set it in the parent message flow and access it in the subflow.
i.e. in the parent message flow:
| Code: |
SET Environment.Variables.decisionKey = 'HIGH';
in the subflow:
-- Or whatever logic you want to apply here
IF Environment.Variables.decisionKey = 'HIGH' THEN
SET OutputRoot.XMLNSC.myMessage.quantity = 1;
ELSE
SET OutputRoot.XMLNSC.myMessage.quantity = 10;
END IF; |
