Exported nested collection only saving schema, not data?

Question

Robin proposed an answer of exporting multiple collections into one:

It seems to work as long as you immediately import - this is because the collection is still in memory.  If you exit the app (or clear the collection), then only the schema can be loaded because the data itself isn't saved.
When I look into the .zip file, I see that the schema is being written but no underlying data.
Perhaps I'm doing something wrong and that's why I'm only getting the schema?
I would be happy to share the project I've been working on if that would be helpful.
Thanks!

thorwm,
   I was initially experiencing the same issue, but it turns out I was just confused (again).   I was building the nested collection during the OnSelect event for the Export control.   Apparently, the OnSelect event happens
AFTER the Export control performs the export.   This can be seen by simply doing the export twice.  
   I have to look at a better way to perform the nested collection process.   Hopefully this is the same issue you are experiencing.
