Multiple instances of editor causes a console error

[arch0njw]

I have a use-case where I need to create multiple editors. When the second editor is created, the following console error is logged:

Uncaught TypeError: Cannot read property 'document' of null     wysihtml5x-toolbar-0.4.5.js:6712
getDocument                                                     wysihtml5x-toolbar-0.4.5.js:6712

This looks like it can be resolved with the following edits:

wysihtml5x-toolbar.js
~line 6711
change

  this.getWindow = function() { return iframe.contentWindow; };
  this.getDocument = function() { return iframe.contentWindow.document; };

to

  this.getWindow = function() { return iframeWindow; };
  this.getDocument = function() { return iframeDocument; };

Nix that. That leads to another issue.

I think I've refined the problem down to dynamically adding a new wysihtml5 editor to the dom. It doesn't seem to know how to resolve what the iframe.contentWindow is when that happens.

Can you give some more details about browser/os and how are you implementing the two editors, so I can reproduce the error?
In /examples folder there is an advanced.html demoing 2 editors on one page (with iframe).

This error appears on Windows and Linux.
Windows: IE, FF, Chrome
Linux: FF, Chromium

The error only happens when adding another editor dynamically. Imagine using a template system like knockout.js and a button click creates a modal with an editor in it. That modal comes from another template and technically did not exist in the DOM until ko's template engine injected it.

ALSO, FWIW, I am not using the editable divs. I am going to try that right now.

The error went away when I used the DIV approach. I'll close this.
