This error happens when page completely loaded.
I have check it in Visual InterDev.
The problem happen there:

if(typeof(window._1$)=='function')window._1$()

I don't use any onload/onunload scripts.
Browser IE 6.0
OS. WinXP SP2
JavaScript Debuger - VisualInterDev 6.0

Thanks.

Please, update your version. We've changed handling of onload and onunload event handlers in recent versions.
You can get it here: http://javascript.cooldev.com/update/.
If error still happens, please, forward your request to javascript@cooldev.com.

Hi,

Some of our clients and one developer's machine here also reports the "Object doesn't support this property or method" error which seems to have something to do with the code in the cooltreepro.js file shown below:

Code:
window._oldCTOnLoad = window.onload;

window._oldCTOnUnLoad = window.onunload;

window.onload = function () {
        var bw = new _BrowserDetector();
        if (typeof(window._oldCTOnLoad) == 'function')
                window._oldCTOnLoad();
}

window.onunload = function () {
        for (var i in window.CTrees)
                with (window.CTrees[i])
                        if (_format.cook)
                                _saveState();
        if (typeof(window._oldCTOnUnLoad) == 'function')
                window._oldCTOnUnLoad();
}

The Developer's machine having the problem seems to be activating the 'function' logic, while everyone else is not.

We were using version 2.7.0 of COOLjsTree, but I've just tried 2.7.5, and the problem still occurs.

Any ideas/suggestions?

Here's the code from our menu page if this helps:

I mentioned in my original post that I have tried upgrading to 2.7.5, and the error IS STILL occurring.

I've just tried emailing information to both your javascript@cooldev.com and jssupport@cooldev.com, both reporting that your domain quota is full.

Looking at the cooltreepro.js script contained in both 2.7.0 and 2.7.5, the same logic exists, so I'm not sure how it would stop the error occurring. And I don't know the purpose of this code in your Tree?

If I remove the if .... == 'function' code from the onload and onunload functions the user's browser doesn't report any error and the menu works correctly. However, I don't know if there are any side effects of removing it, and obviously that would affect support/upgrades in the future anyway.

The problem seems to happen in IE, but not Firefox on her machine, but not at all on my machine, even though our IE versions appear to be identical.

During initialization tree grabs onload and onunload methods. First one is needed to draw the tree at the very first time (for those who forgot to add RedrawAllTrees call). Second one is needed to free some memory (yes, there is a garbage collection, but in IE it is broken or maybe not as good as it should be). These "if" statements call previous handlers, if any.

Sorry, but we can't fix this until we're able to reproduce the issue. If it works for everyone except one machine, then probably that machine must be fixed.
