I managed to narrow down the error. It seems that I am using an array as a
subobject
this.columns=new Array();
then ajax comes and adds stuff:
Object.extend(Array.prototype, {
push: function(o) {
this[this.length] = o;
},
addRange: function(items) {
if(items.length > 0)
for(var i=0; i<items.length; i++)
this.push(items[i]);
},
clear: function() {
this.length = 0;
return this;
},
shift: function() {
if(this.length == 0) return null;
var o = this[0];
for(var i=0; i<this.length-1; i++)
this[i] = this[i + 1];
this.length--;
return o;
}
}, false);
and now this.columns.length is not the same as before and if I do a for loop
through the array I also get the functions added:
for (int c=0; c<arr.length; c++) alert(arr[c]);
That can't be right, can it? I am trying to replicate the problem in a more
simple manner, but I couldn't do it yet.
