FCKeditor is not showing for only event content type

I am struggling with the same problem. There are two other similar questions within Issues but not one of them has been answered. I'm not sure if those of us who are struggling are considered too stupid to bother with or if the question is just too difficult to answer. Either way, it would be very nice if there was a change of heart and someone came to our aid.

I made a quick search for 'event' and only found #690574: When creating event using event module, WYSIWYG editor does not appear until after preview, which I closed because I and another participant were unable to reproduce the problem. I can assure you we don't consider any of our users stupid at all. It's however easy for an issue to get pushed to the back of the issue queue when it stalls like the one above did, and we only have our spare time to put into this module. (I would absolutely love to work on it full-time, but I can't make a living doing that. Not now at least...)

I re-tested this just a minute ago using Wysiwyg 6.x-2.x-dev (2010-Sep-25 but 2.1 should work too), FCKeditor 2.6.6, Event 6.x-2.d-dev (2010-Jul-11) and the Event content type it creates, I still can't reproduce the issue.
Any information you can provide about your setups and/or script errors produced will be very valuable.
Exactly which version of Event module are you using?
Are you using any of its extension modules?
Are there any script errors on pages where the editor should appear?
If you inspect the source code of the radio-buttons used to create the input format selectors (or the div showing its description if only one is available), do they have classes starting with "wyswiyg-"?
If you inspect the DOM, does Drupal.settings.wysiwyg.configs.fckeditor contain anything at all? (There should be at least one sub-object per input format FCKeditor was assigned to, containing settings for the editor profiles.)

What other modules do you have installed?

Wysiwyg has no settings per content type, it's all about per input format, so if it's working for one content type it should be working for all of them. One exception could be when the fields do not use filter_form() to create the format selectors, or put them under a FAPI key other than 'format', which can and probably will prevent Wysiwyg from recognizing that the field is "input format enabled" at all in D6.

Sorry, without further information this issue can only be closed as not reproducible.

Feel free to re-open this issue if you want to provide further information. Thanks.
