Thanks for this. Also you  are right. This was a code from the time where we begin with javaScript .

My column definition (a work in progress) looks like this:

{
    name: "Date",
    index: "Date",
    width: 72,
    formatter: 'date',
    formatoptions: {
        srcformat: 'm/d/Y',
        newformat: 'm/d/Y',
        defaultValue:null
    },
    editable: true,
    editrules: { required: true, date: true },
    editoptions: { 
        size: 20, 
        dataInit: function (el) { $(el).datepicker(); }
    }
},

I was able to work-around the bug by changing the function block at line 5980 like so:

daysArray = function(n) {
	var i, a = new Array(n);
	for (i = 1; i <= n; i++) {
		a[i] = 31;
		if (i==4 || i==6 || i==9 || i==11) {a[i] = 30;}
		if (i==2) {a[i] = 29;}
	}
	return a;
};

On a related note, why pass 12 in? The number of months in a year isn't likely to change in our lifetime.

in which case this function can be:

daysArray = function() {return new Array(0,31,29,31,30,31,30,31,31,30,31,30,31)}

Error occurs in Chrome and Firefox. No other browsers tested.

Best regards.

A simple test case is greatly appreciated.

Appears that "this" needs a JQuery-reference.

I changed "this" by "$(this)" (4 times in this function) and the function works.

Same error reported in the help-forum :
