I have a message flow that checks for values and then throws a user exception if the values are invalid. I am not getting my expected results. Can someone help me understand what I am doing wrong?
Thanks!! Lisa
Here is my code: The input value for FIL1 = XX the input value for FIL2 =MM
CODE:
IF ( FIL1 <> 'TR' ) THEN
SET OutputLocalEnvironment.Errors.FIL1 =
('Invalid Data sent from System.');
IF (FIL2 <> 'MM') THEN
SET OutputLocalEnvironment.Errors.FIL2 =
('Invalid Time sent from System.');
DECLARE C CHAR;
SET C = CARDINALITY(OutputLocalEnvironment.Errors.*[]);
IF C > 0 THEN
DECLARE ALLERRORS CHAR;
SET ALLERRORS = (OutputLocalEnvironment.Errors.FIL1 || ' ' ||
OutputLocalEnvironment.Errors.FIL2);
Throw user exception values (ALLERRORS);
END IF; |

Haven't got time to actually run this, but I know it will fail if one of the error conditions DON'T happen. Concatenating strings that don't exist can lead to the result being set to NULL.
Cheers,

Thanks! In this case, the first error condition exists and it's still not working. Any ideas?

Try this:
SET OutputLocalEnvironment.Errors.FIL1 = ' ';
SET OutputLocalEnvironment.Errors.FIL2 = ' '; -- just to avoid null if not allocated any value in the code. Its basically initializing the variables.
and then your code.

DECLARE C CHAR;
SET C = CARDINALITY(OutputLocalEnvironment.Errors.*[]);
IF C > 0 THEN
DECLARE ALLERRORS CHAR;
SET ALLERRORS = (OutputLocalEnvironment.Errors.FIL1 || ' ' ||
OutputLocalEnvironment.Errors.FIL2);
Throw user exception values (ALLERRORS);
END IF;

Also looking at your code what i understood is :
If -> IF - End if;
i think this should be
If ->IF -> end if -> end if;
thanks,

I am using this processing in a Route To Message flow. In order to use the OutputLocalEnvironment, I need to check the LocalEnvironment and Message check box on the Advanced tab of the Compute node. When I do this I get an error saying that the Route to is unable to locate the Label node.
Is there anything else I can use to pass variables from one node to the next?
Thanks, Lisa |

Since you have to put the Label to route to into the OutputLocalEnvironment anyway, I suspect the problem is that you're doing something wrong, or not setting the destination in your error handling.

There's always Environment instead of OutputLocalEnvironment. It's usually better to put your stuff into Environment.Variables, or Environment.<MsgFlowName>.Variables or some subtree that other people won't (or shouldn't!) touch, just so you're safe working with subflows and etc.
