Use data: $(form).serialize() instead of data : JSON.stringify(model)

i can't use $(form), i need to post a js variable. – Courtois Olivier Jan 07 '13 at 10:18
Try changing the date format before the ajax post. The following link could be helpful.[link]http://stackoverflow.com/questions/2573521/how-do-i-output-an-iso-8601-formatted-string-in-javascript – Rifaj Jan 07 '13 at 12:05

I have found my problem, in the view model i have :

public class MyViewModel
{
[MaxLength(10)]
public DateTime MyDate { get; set; }
}

the MaxLength attribut cause the error

I just had this problem today, I'd commented a property out, but not the DataAnnotations above it...and there was a DateTime below...drove me crazy for a couple of hours. Thanks for posting your own solution for the greater good. – MongooseNX Jan 18 '14 at 00:15
