I have a BLOB set in my environment variables. I want to set and propagate propagate this from my out terminal and it should be available as a message to the next node. I am writing the following piece of code but this does not seem to be working.
BROKER SCHEMA com.ibm.einvoicing.esql.common
CREATE COMPUTE MODULE setPrimaryDocFromVariables
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
CALL CopyMessageHeaders();
CALL CopyEntireMessage();
SET OutputRoot.BLOB.BLOB = Environment.Variables.EInvoicing.HRInvoice;
PROPAGATE TO TERMINAL 'Out';
RETURN FALSE;
END;
CREATE PROCEDURE CopyMessageHeaders() BEGIN
DECLARE I INTEGER 1;
DECLARE J INTEGER;
SET J = CARDINALITY(InputRoot.*[]);
WHILE I < J DO
SET OutputRoot.*[I] = InputRoot.*[I];
SET I = I + 1;
END WHILE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
END;
END MODULE;
Please provide some help here. |

1) Don't use BOTH of these
| Code: |
CALL CopyMessageHeaders();
CALL CopyEntireMessage();
|
2) You probabl only need
| Code: |
CALL CopyMessageHeaders();
|
as you are adding a BLOB to the OutputRoot.
3) This
| Code: |
PROPAGATE TO TERMINAL 'Out';
RETURN FALSE;
|
Is also where you are going wrong. There is No Terminal 'Out'.
(look at the case)
4) This
| Code: |
PROPAGATE TO TERMINAL 'Out';
RETURN FALSE;
|
when you fix the terminal name is the same as

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Thanks smdavies99 a lot for rectifying it. I am able to get through this now.
However, I realized, that I was using a wrong piece of code as following
| Code: |
PROPAGATE TO TERMINAL 'out';
RETURN TRUE; |
I was propagating explicitly as well as returning a 'True'. I observed that this was causing NullPointerException some where down the message flow.
When I corrected it to the following piece of code, my flow executed smoothly.
| Code: |
PROPAGATE TO TERMINAL 'Out';
RETURN FALSE; |
So, I was just wondering what was the problem with the faulty piece of code. Is it like if I propagate explicitly and return a TRUE, will it propagate the message twice which causes some problem down the message flow?
Kindly throw some light on it. |

Yes.
And you have to think about what message is being propagated the second time. |
