Not An Array

Test Page for bug in Firebug 1.2.0b3 - 1.2.0b15

// Constructor
function NotAnArray(o) {
	if (o.constructor === Array) {
		this.data = null;
	} else {
		this.data = o;
	}
}

// Add some prototype things
NotAnArray.prototype.toString = function () {
	return 'I\'m not an array!';
};

NotAnArray.prototype.whatAmI = function () {
	return 'Totally not an array.';
};

// Instance
testValue = new NotAnArray('blah');
	

console.log(testValue);

Expected:

I'm not an array! data=blah

Received:

[ ]

Fix:

Error exists in lines 372 - 382 in reps.js.

Existing code is using YUI "YAHOO.lang.isArray" function from YUI 2.2.2.

Updating this function to use the equivalent code from YUI 2.5.1 resolves the issue.
