Hi Frederic,
Thanks for your reply.
I have read the above link and understand why the validation behaves in the
manner it does but the issue is with the binding of the properties.
If all the values of the row are empty then no binding of the properties takes
place. This means that the values can never be blank.
Take the example with a List of Person objects.
List<Person> persons;
Person{
name: String;
age: String;
}
If I wanted to blank one item in the list i.e. set name to "" and age to "",
stripes will remove these parameters from the list before the binding. This
neans this item in the list is never touched and the values remain as
originally set.

> Hi,
