I can hit the "back" button and my new field is added, but trying to do anything else in the View pages will result in that error. Something is bjorked with this module.

Getting the same

Had this too before. Got the same when disabling ajax?

Getting the same problem. Additionally, the FullCalendar display plugin 'Settings' link does nothing.

same issue

I'm getting the same when editing field settings. Also cannot even get to edit screen for the date field - nothing happens on clicking the link.

Tried disabling AJAX on the views UI as @aspilicious suggested in #2 and got a similar white screen error on saving the settings.

However, going back to the view AJAX was disabled and I was then able to edit the fields. Then re-enabled AJAX after changes were made. This might help some whilst the root issue is being fixed.

Same error - very strange. nothing in watchlog. Does not seem to add the field with back button though. using latest full-calendar in libraries. Not sure where to go from here....

I had a similar error and in order to solve it I re-created the view following the exact instructions found here: http://drupal.org/node/1237808.

I am running drupal 7.17 and the latest stable modules.

I had a mysterious error where the entire calendar disappeared, and was replaced by an exposed date filter. After some experimentation, it turned out that the bug was related to ajax being enabled on the view.

My guess is that FullCalendar either requires some elements that are hidden if ajax is used, or that FullCalendar uses some ajax stuff that conflicts with Views' ajax.

Also: This issue *might* be related to #1803770: Uncaught TypeError: Cannot read property 'views_dom_id:***' of undefined .

Same problem, has anybody found a solution to this?

I think the problem is with the FullCalendar plugin directory, the plugin is supposed to be in /sites/all/libraries/fullcalendar/fullcalendar.js , /sites/all/libraries/fullcalendar/fullcalendar.min.js and /sites/all/libraries/fullcalendar/gcal.js. So when you download the Full Calendar plugin, extract it and copy the fullcalendar directory and paste it in the /sites/all/libraries directory, please do not copy the demos and jquery directories (just like in the README.txt of the fullcalendar module). If you have these directories in your plugin directory remove them they are probably the likely culprits for the error. Try that.

the same problem.
p.s. I have fullcalendar in /profiles/my_profile/libraries/fullcalendar folder

problem appears when AJAX setting is set to "yes"

Using JQuery Update, switch your version of JQuery from 1.8 to 1.7 (see comment #1: https://drupal.org/node/1869988). This solved a similar problem that I was having.

AllanTheDream, that was helpful... but not for this issue. :-) I was having two problems: the one posted above, and also that the calendar wasn't displaying at all on the page. Getting rid of the demo and jquery directories made the calendar display on the page -- hooray.

Still getting baloney similar to the first post above anytime I try to edit the " FullCalendar: Google Calendar" field of my view, though. So, for example, I click to edit the field and then paste in the google calendar address and click apply. I get a long error as above. I click 'back' and the 'feed url' field is blank again. So my fullcalendar is permanently blank, since I have no way to link it to my google calendar.

I've tried turning ajax on and off and I'm getting the same error either way. Guess next I'll try webs.com.mt's advice above and recreate the view to see if that gets me anywhere.

EDIT: Looks like my issue is actually the same as https://drupal.org/node/2129363 -- which so far has no responses. I'll post there.

Try clearing your cache. I'm doing that solve a lot of weird problem.
