I had a Node, which includes an Image field.

I wanted to Clone, but to change the image, as well as a few other details.

Got this as soon as I chose "remove" image :- 

   *  Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'node_form' was given in drupal_retrieve_form() (line 771 of /home/likalco/public_html/core/includes/form.inc).

I went ahead and saved anyway and the Node cloned, but with the original image.

I was then able to change the image by subsequent editing.

I think all is coming from the first warning, but I can't see why its gives an error since the callback function called is the same as in a usual node addition.

Seems quite similar to this issue: http://drupal.org/node/1105624

I patch it through another attached module that manage image field cloning. It is a quick/strange/ugly patch since the [files] attribute was in the $form[build_info][args] array and I added in the $form[build_info][files].

A recheck of this module (and of image management) from its creator would be welcomed. I am not sure it duplicate images properly.

Title: Can't change images » Same issue

Same issue here.

Also happens on clean drupal install.

Install with standard install profile. Cloning the default "article" content type and changing the image will throw this error.

Anybody a solution?

Title: Same issue » Ajax error when changing files in cloned node

Just a note: by settings the clone node settings in "admin/config/content/clone" to "Save as a new node then edit" we can prevent the error from happening.

I was having this same issue with Ctools 7.x-1.0-rc1 (it was actually in Page Manager, per the link in #3). I updated to the latest 7.x-1.x-dev (2012-Jan-23), and the error has gone away.

I had the same issue and fixed it by patching the module node clone.

Just added the line on top of the file clone.pages.inc:

require_once(drupal_get_path('module', 'node') . '/node.pages.inc');

PS : it seems that module_load_include doesn't work and I didn't find why)
