Exports should work as passthrough - no representation needed in the client - it makes sense to only render 1000 or so rows. But as I can see… only the selected rows will be exported. If only 1000 rows (or as set in preferences) can be selected in the client, it won’t be possible to export more. Except you add checkbox or something that says: Export all found records (instead of selected). I don’t know tryton well enough to know how to “solve” this issue.
Thanks for your thoughts,
