Hey guys,
That error has indeed been fixed in the dev branch so thank you.
However I've uncovered more problems.
1) the tuple example does not create the specified index in the database.
2) How do you use the +unique+ and other singletons for indexes? I don't
get it...
3) There is no >multi word for updating more than one row at once - which I
think is of high importance.
I tried adding the >multi word myself based on >upsert but encountered
"Invalid object size" error.
The exact changes I made are attached.
Cheers.
