I am using a ctools content type plugins to render a custom form that will have only one submit button.

The submitbutton will switch an eck entity field (boolean) from 0 to 1 and back (if pressed again, of course).

I have defined my ctools content type plugin, form (with ajax callback) and a submit handler

When i tested it with a hook_menu path, all was fine and it worked.

Since i have put it in a ctools content type, no luck.

Any help would be very much appreciated!

Ps: What would be the best place to put my database logic? The submit handler?

Thanks a million!

$plugin = array(   'single' => TRUE,   'title' => t('Project isClient'),   'description' => t('Project isClient AJAX plugin'),   'category' => t('Project'),   'render callback' => 'project_isclient_ajax',   'defaults' => array(), );  function project_isclient_ajax() {   $pane = new stdClass();   $pane->title = t('Project isClient');   $pane->content = drupal_get_form('project_isclient_form');   return $pane; }  function project_isclient_form($form, &$form_state) {   return array(     'submit' => array(       '#type' => 'submit',       '#value' => t('Subscribe'),       '#ajax' => array(         'callback' => 'project_isclient_ajax_submit',         'wrapper' => 'project-isclient-form',         'method' => 'replace',         'effect' => 'fade',       ),     ),   ); }  /**  * Ajax callback function.  */ function project_isclient_ajax_submit($form, $form_state) {   // Dummy/dumb validation for demo purpose.   return 'works!'; } 

A little after posting this, i found AJAX calls in CTools Content Type Plugin? which states that ctools handles ajax forms differently. I checked using blocks, and this appears to be correct. In a block my callback works.
