hi,
I have a message flow thats converts TDS to generic XML.When I deliberately misspell the reference to a element in the message set in my transform node,the node does not throw an exception.It just doesnt assign a value to that perticular XML element.Am i missing something here.Is it not supposed to throw an exception when it sees a incorrect reference(by the way I do have a try catch node before the transform). |

Working as designed.
You 'may' be able to get an error thrown by using some of the validation options.
Cheers,

Hi
If you misspell in your reference broker looks for the misspelled element and doesn't find any.it continues processing with out throwing an exception.you can see this by debugging the flow.If you are referencing element which doesn't exist,it simply says Failed to navigate to path element becaue it doesn't exist and continues with the next line of your code.If you assign this to your XML element.You won't find this XML element in you output,becaue it is assigend to the element which doesn't exist means NULL.
Thanx

| Okay.Are there any conditions in which the transform node throws the message back to the trycatch node like what if I populate the environment exception list. |

There is a 'throw' ESQL statement that will cause the node to exit out of the 'failure' terminal - which if not connected will propogate back to the try/catch node.
You can also get exceptions thrown automatically when your code encounters runtime errors - like going past the bounds of an array, or assigning to a NULL reference, or assigning a string to an integer (or other such conversion failures).
But merely putting stuff into the ExceptionList tree will not cause the node to propogate out to the 'failure' terminal.
