uncaught exception: Permission denied to get property Object.constructor

seems you are getting “uncaught exception: Permission denied to get property Object.constructor” while you are  executing some javascript which was instantiating some objects and during that time it stucked with some exception.

for example

function get(pUpdate, pUrl, pParams) {
new Ajax.Updater(pUpdate, pUrl, {parameters: pParams});
}

if you want to regenerate this exception you can invoke this function with the following arguments -

get(“abc”, “http://abc”)

so why this crap ?

the main reason is in your code where you mentioned about “parameters” and which is not supposed to be null. you better write the following code -

function get(pUpdate, pUrl, pParams) {
var options = new Array();
if (pParams != null) {
options["parameters"] = pParams;
}

new Ajax.Updater(pUpdate, pUrl, options);
}
that will take away your javascript exception.

best wishes,
