Hi,

Using the latest CSV driver source I was creating a standalone application using ETL to transform contents from a plain XML model to a CSV model.

The CSV model has a header but was otherwise empty.

Then ETL attempted to persist the contents to the CSV file but it failed:

Exception in thread "main" java.util.NoSuchElementException
	at java.util.LinkedList.getFirst(Unknown Source)
	at org.eclipse.epsilon.emc.csv.CsvModel.createInstanceInModel(CsvModel.java:323)
	at org.eclipse.epsilon.emc.csv.CsvModel.createInstanceInModel(CsvModel.java:1)

	at example.transformation.xml2csv.XmlCsvEtlStandaloneExample.main(XmlCsvEtlStandaloneExample.java:31)

Looking at the source of CsvModel I implemented a short fix by defining a list holding the header information - PFA the solution that worked for me.

Martin
