Can we access any other child except ${ExceptionList} in Trace Node? If yes, how? I tried {ExceptionList.RecoverableException.Text} for example and it did not work.
Does it mean only the root ( ExceptionList) is accessing from within TraceNode?
Thank you for your help |

Why do you want to access this in Trace Node? When you give ${ExceptionList}, the child trees will also be shown in the trace file.
Child trees can be accessed explicitly in the compute nodes.

What does it mean "did not work"?
You can do ${Root.Child.Child}, so you should be able to do ${ExceptionList.Child.Child} - but maybe you didn't get your children right.

This is the strcture of the exception tree structure as given in document.
| Quote: |
ExceptionList {
RecoverableException = { 1
File = 'f:/build/argo/src/DataFlowEngine/ImbDataFlowNode.cpp'
Line = 538
Function = 'ImbDataFlowNode::createExceptionList'
Type = 'ComIbmComputeNode'
Name = '0e416632-de00-0000-0080-bdb4d59524d5'
Label = 'mf1.Compute1'
Text = 'Node throwing exception'
|
If this so, why can not do the follwoing in TraceNode?
${ExceptionList.RecoverableException.Text},
However, when I gave that expression in TraceNode it was displayed as it is in the log produced by tracenode. I am aware that I can not manipulate the exceptionList tree in Tracenode but can not even we use it?
thanks |

What does that mean?
What do you get when you put in that Expression?
What do you expect to get?

I mean when I gave that pattern in tracenode I got the same patter displayed in output instead of the value of that pattern.
I got ExceptionList.RecoverableException.Text in the out put. I was expecting some value like [Text = 'Node throwing exception'] as given in the document. Even, if there was not an exception and the value of that attribute wan null, it should be zero/null instead of displaying the pattern itself. Is my expectation wrong?
thanks |

Hi jeevan,
Did you give the '$' before the path and put the path inside flower brackets...you would get the text you entered when these were missing...

This is the pattern in Tracenode
${Root.MQMD.MsgId}
${ExceptionList} ${ExceptionList.RecoverableException.Text} |
