After enabling view quiz_results, and when I click on Data export tab, it show me empty tab. Root cause is Data export module is not installed. Quiz module should contains dependencies for views_data_export module.
Also, I've got notice on some other part of site (for example, on Feature diff tab).
Notice: Undefined index: views_data_export in views_plugin_list() (line 277 of /home/sitename/public_html/sites/all/modules/contrib/views/views.module).
Notice: Undefined index: views_data_export in views_plugin_list() (line 278 of /home/sitename/public_html/sites/all/modules/contrib/views/views.module).
Notice: Undefined index: views_data_export_csv in views_plugin_list() (line 277 of /home/sitename/public_html/sites/all/modules/contrib/views/views.module).
Notice: Undefined index: views_data_export_csv in views_plugin_list() (line 278 of /home/sitename/public_html/sites/all/modules/contrib/views/views.module).So, quiz_results is not valid without views_data_export. Easiest solution is to put
dependencies[] = views_data_export
into info file.
