Ajax, WYSIWYG API, TinyMCE, CKeditor disappear after preview

Same problem!

Subscribing

Actually.......seems like disabling Ajax WYSIWYG plugin did the trick :)

Only tested on Firefox 3

Same here on FF3.

Im using CKeditor and getting this bug too. I can click "Disable WYSIWYG-editor" and then "Enable WYSIWYG editor" and all works fine again.

When enabled ajax for comments and use ckeditor I had message «Comment is required» when click on submit button in comment form. ajax for fckeditor module isn`t work with ckeditor. What should I do to use ckeditor with ajax module correctly?

I switched to BBCode :)
Using BBCode also enables the use of geshiflter.

I'm having this problem again :(

This is still happening (and I need the "Ajax plugin - wysiwyg" module).

You can try solving it with JS Alter, jQuery Form Update and jQuery AOP. These modules require no configuration: just enable them to fix the problems.

this don't work for me

This happened to me too while testing the validation & error messages.
Looking into the code, I saw that the wysiwyg plugin only detaches the editor when the form is submitted and does nothing afterwards, regardless of which happens to the form. When it is just submitted then everything is OK but if the form returns with a preview or an error then the editor still remains detached.

The full wysiwyg plugin is as follows: (file: ajax_wyswyg.js)

Drupal.Ajax.plugins.wysiwyg = function(hook, args) {
  var p, e;
  if (hook === 'submit') {
    if (Drupal.wysiwyg && Drupal.wysiwygDetach) {
      for (w in Drupal.wysiwyg.instances) {
        p = Drupal.wysiwyg.instances[w];
        e = $('#' + p.field);
        Drupal.wysiwygDetach(e[0], p);
      }
    }
  }
  return true;
}

Then, I added a second test before the final "return true;" statement so the function responds to the hook 'message' too:

...
  if (hook === 'message') {
    if (Drupal.wysiwyg && Drupal.wysiwygAttach) {
      for (w in Drupal.wysiwyg.instances) {
        p = Drupal.wysiwyg.instances[w];
        e = $('#' + p.field);
        Drupal.wysiwygAttach(e[0], p);
      }
    }
  }
...

So if any "message" (preview, error, success, warning) comes back the plugin re-enables the editor with wysiwygAttach().

Fixed, thanks to @cluke009's contribution at https://github.com/brendoncrawford/drupal-ajax/pull/2

Fixed issue by using javascript code

removed old CKEDITOR instances for the text area.

$(document).ajaxComplete(function() {
  if(CKEDITOR.instances["edit-message"]) {
    delete CKEDITOR.instances["edit-message"];
    $('#edit-message').ckeditor();
}
});

where 'edit-message' was id of textarea.
