I am seriously considering biting the bullet and replacing the Xinha HTMLEditor with CKEditor. It seems the CKEditor folks are working on making their editor play nice with jQuery.

Found list of links on the topic of building plugins for CKEditor:

http://stackoverflow.com/questions/1957156/ckeditor-how-to-add-a-custom-button-to-the-toolbar-that-calls-a-javascript-funct/1966239#1966239

If I do this I'll need to redevelop the linker and imagemanager plugins.

Another option might be the TinyMCE editor which, unlike CKEditor, has a large number of existing plugins.

So I had a function:

function fv_loadUrl( parms )
{
var elem = parms.elem;
var href = parms.href;
window.location.href = href;
return true;
}

Works like a champ in FireFox, but not in MSIE 6. I read a post that speculated the script was terminating before the page could load. Changing the return true; to return false; solved the problem.

A technical article on Javascript Closures.

And an article describing an approach to dealing with closure memory leaks.

And an article describing a tool to track down memory leaks in MSIE.

An article over at slashdot.org referred to a commercial/open source rich user interface library called ExtJS available at: http://www.extjs.com/.

As of this writing it is dual licensed under the GPL and a Commercial License, similar to the way formVista is licensed.

After a cursory glance it seems like a fairly complete toolkit, but at this point I'm committed to continuing on with jQuery for formVista.
