[greasemonkey-users] Error: Greasemonkey access violation: unsafeWindow cannot call GM_getValue.

[Adam]

I work in the IT field, and unfortunately we're stuck using a web help
desk written a long time ago. It's very poorly written HTML, and the
help desk lacks a lot of functionality. It'll probably be at least a
year before we can get another web help desk, so I've been working on
a Greasemonkey script to improve the web help desk for the time being.
However, I'm getting an error using GM_getValue. I've already read
http://wiki.greasespot.net/0.7.20080121.0_compatibility but it didn't
seem to help. I would love some troubleshooting. Thanks! Here is my
code:

// Add jQuery
var GM_JQ = document.createElement('script');
GM_JQ.src = 'http://www.lamintak.com/misc/jquery.js';
GM_JQ.type = 'text/javascript';
document.getElementsByTagName('head')[0].appendChild(GM_JQ);

// Check if jQuery's loaded
function GM_wait() {
        if(typeof unsafeWindow.jQuery == 'undefined')
{ window.setTimeout(GM_wait,100); }
        else { $ = unsafeWindow.jQuery; letsJQuery(); }
}
GM_wait();

// All your GM code must be inside this function
function letsJQuery() {
        // Loop through each row in the main table and add the "Will Be
Addressed..." headers and cells

        $("table.TableBody tr").each(function() {
                var rowhtml = $(this).html();

                if (rowhtml.indexOf("Support Personnel</a></td>") != -1) {
                        var AddressHeader = $("<td>*Will Be 
Addressed...</td>").attr('id',
'WillBeAddressedHeader');
                        $(this).append(AddressHeader);
                }
                else {
                        var AddressCell = $("<td></td>").attr('class',
'WillBeAddressedCell');
                        $(this).append(AddressCell);
                }
        });

        // Loop through each "Will Be Addressed..." cell and add the text
fields

        $("table.TableBody td.WillBeAddressedCell").each(function() {
                var InputField = $("<input type=\"text\">").attr('class',
'WillBeAddressedInput');
                $(this).append(InputField);
        });

        // Get the saved value and put it in an array

        WillBeAddressedString = GM_getValue('WillBeAddressed');
        WillBeAddressedArr = new Array();
        if (WillBeAddressedString) {
                WillBeAddressedArr = WillBeAddressedString.split('|');
        }

        // Loop through the text fields that were just created

        var count = 0;
        $("input.WillBeAddressedInput").each(function(){
                // Add the IDs

                $(this).attr('id', 'WillBeAddressedInput' + 
WorkOrdersArr[count]);

                // Add any saved values that might exist

                for (i in WillBeAddressedArr) {
                        if 
(WillBeAddressedArr[i].indexOf('WillBeAddressedInput' +
WorkOrdersArr[count]) != -1) {
                                var InputValue = 
WillBeAddressedArr[i].split('~!');
                                $(this).attr('value', InputValue[1]);
                        }
                };

                count++;

                // Make it so that whenever the text field goes out of focus, 
the
                // "WillBeAddressed" Greasemonkey variable will be updated

                $(this).blur(function() {
                        // Get the latest version of the "WillBeAddressed" 
variable, just
in
                        // case it was changed in a different tab

                        WillBeAddressedString = GM_getValue('WillBeAddressed');
                        // Error: Greasemonkey access violation: unsafeWindow 
cannot call
GM_getValue.
                });
        });
}
