I still seem to be missing something. Must be obvious but I can't see it.
I use the example code you showed, and the errors dict shows the values and
form.errors is now an empty dict, but the error messages still get displayed
in the old manner without me doing anything. It's as if the error messages
are displayed from somewhere else, but I can't see where.
I put this line of code towards the top of my view:--
{{(errors,form.errors)=(form.errors,dict())}}
Then I display errors and form.errors to make sure they have what I expect.
Form.errors is empty. Now I would expect not to see any errror messages
unless I place them myself. Unfortunately, they still appear in the old
position as though I had made no changes.
What have I overlooked.
