Yes I tried it, and it gives the same error, because in the configuration 
file I have:

'Controller::HTML::FormFu' => {
constructor => {
default_args => {
elements => {
Date => {
constraints => [
{
type => 'DateTime',
parser => {strptime => '%Y-%m-%d'},
},
],
},
DateTime => {
constraints => [
{
type => 'DateTime',
parser => {strptime => '%Y-%m-%d %H:%M:00'},
},
],
},
},
},
},
}

I see that there is constraints => [
so the constraints key is not a hashref indeed, and I think that this might 
be the cause of the error, but I think it shouldn't be a hashref, because 
there may be more constraints.

This code was working until some time ago, but now it gives that error.

Should I change the data structure for these settings?
If yes, please tell me which is the correct syntax.

If you want, I can send you a sample Cat app which gives that error.

Thank you.

Octavian
