TinyMCE: TypeError: t.win.document is null in Firebug Console

I came across this error on a site I was helping to troubleshoot today and with a little Googling found it happens when you move the DOM containing a TinyMCE editor to another place in the document: TinyMCE loses it’s reference to that original element.

To get around this, showing or hiding the editor won’t work, instead destroying the element before you move it and recreating it (same as the previous post) does the trick:

tinyMCE.execCommand('mceRemoveControl', false, 'idOfElement');
// move DOM element
tinyMCE.execCommand('mceAddControl', false, 'idOfElement');

Removing all TinyMCE editors on the page for reinitializing

Sometimes, one needs to remove (not hide) all TinyMCE editors on the page to run a modified version of the global tinyMCE.init code again. This is the best way I’ve found to do it so far:

var i, t = tinyMCE.editors;
for (i in t){
    if (t.hasOwnProperty(i)){
        t[i].remove();
    }
}
// new tinyMCE.init code here

Additionally, you can “destrory” and “recreate” specific editors via:

tinyMCE.execCommand('mceRemoveControl', false, 'idOfElement');
tinyMCE.execCommand('mceAddControl', false, 'idOfElement');

If anyone knows a better way, post in the comments.
