Hi,
actually the implementation is more for "download" of real data and use it for demo as CSV. Therefore the way of creation of the CSV file is.
1. attach real data source in your app
2. open initial view editor
3. click the (new in 1.6) button "Download as CSV.
then, the CSV will be created with 3 files
* CSV file with data
* metadata file (as Tammy writes, it is required for the system to understand the CSV data)
* xml data with currect initial iew state (optional if existing)
Of course, you can parse the metadata file and find a way to create such for your CSV (should bot be too complex, just try)
