I would expect response.flash to look a bit strange in 2 ways: a Rows
object is not a simple string or number, but will display as a conversion
to string, something like
supplierchoice.idsupplierchoice.productnamesupplierchoice...
1 long name of 10
product
(I was expecting json format, but it appears the pretty printer is used)
And then you set response.flash in the for loop, but it isn't returned
until after the for loop is done, so it will only show the last result.
