John,
Basically if you are trying to expose the errorlist out of the convertToValues (set validate=true,maxErrors=-1,errorArray=true)then you will all see the errors in the pipeline wrapped in the errorArray.
So to extract the error data,create a document(this should have the same fields as shown in the errorList in the pipeline) and map the errorArray to doc_ErrorList(DocumentReferenceList)this will have the errors thrown by flatfile validation.
In the nextstep branch on the isValid(if false)then loop thru the doc_ErrorList and format it to a template/string and generate email report or what ever your error handling process is.
