Hi all,
Well after much banging of head against desk, tracing through code, I
came to find that it was a problem whereby any false value wasn't
being pushed onto an array. This was due to a nasty piece of code in
fValidate (for adding push to Arrays for IE):
if ( typeof Array.push == 'undefined' )
Array.prototype.push = function()
{
var arg, i = 0;
while( arg = arguments[i++] )
{
this[this.length] = arg;
}
return this.length;
}
So no problem in MochiKit. Just some bad coding in another library.
Cheers
Bryce
