I have COOLjsTree 2.7.0 pro and when add prototype script (http://openrico.org/dist/1.1.2/prototype.js) to web page menu is no longer shown. I suspect it is because of prototype special handling of $ sign, but this is only the suspicion.

Can you confirm that new version will work with prototype script?

Thanks, Miro

If it work if you will include prototype.js after cooltreepro.js. Our future versions will work with prototype.js without any order requirements.

I'm using prototype.js after cooltreepro.js and I'm still having this problem, but I do call RedrawAllTrees() at the end of my body code. We have version 2.6.0, which was provided to us when we made our purchase recently. Will upgrading to 2.8.4 fix this, or should we wait for the future version?

The tree still does not work correctly (can not perform expansions) in pro 2.8.5, with prototype.js included after cooltreepro.js. It's fine if prototype.js is removed.

Please, try the latest version - 2.8.7.

i don't see a 2.8.7 version of cooljstree pro in the customer care center - just the 2.8.7 version of standard on the downloads page. i need pro since i'm performing relative positioning of the tree.

unfortunately it's still not working; i get a "script is busy" javascript alert dialog and eventually javascript errors indicating it can't see the cooltreepro.js functions. html follows:

<html>
<head></head>
<body>
<script type="text/javascript" src="/lib/extern/cooltree/cooltreepro.js"></script>
<script type="text/javascript" src="/lib/tree_format.js"></script>
<script type="text/javascript" src="/lib/tree_nodes.js"></script>
<script type="text/javascript" src="/lib/extern/ibm/prototype.js"></script>
<script>
var myTree = new COOLjsTreePRO("tree1", TREE_NODES, TREE_FORMAT);
myTree.init()
</script>
<script>RedrawAllTrees();</script>
</body>
</html>

i've confirmed the version of cooltreepro.js:
// Title: COOLjsTree
// URL: http://javascript.cooldev.com/scripts/cooltree/
// Version: 2.8.7a

and prototype.js:
/* Prototype JavaScript framework, version 1.3.1

actually i need to load prototype.js in the head, but i'm unable to get it to work in the body first.

You're using prototype 1.3.1 which defines "Object.prototype.extend". So, it extends every object instance, and makes hashes partially unusable - nobody can use "for (var key in hash) { ... }". Believe me, this is extremely bad practice, and it is incompatible with almost every major script library. That's why you can see the following statement as a "best practice" from some gurus: do not use prototype.js - it modifies Object.prototype.

We will never make our code compatible with prototype 1.3.1.

Newer versions of prototype (1.4.0, 1.5.0) behave much more politely, and no conflicts arise. So, upgrade.
