Having duplicate entry error with Panelizer module

Question

I installed the Panelizer module and enabled it for a specific content type. When trying to add new content, I get a duplicate entry error as follows :

PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry 'node-196-197-page_manager' for key 'PRIMARY': INSERT INTO {panelizer_entity} (entity_type, entity_id, revision_id, no_blocks, css_id, pipeline, did, view_mode, css_class, title_element, link_to_entity) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_8, :db_insert_placeholder_9, :db_insert_placeholder_10); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => 196 [:db_insert_placeholder_2] => 197 [:db_insert_placeholder_3] => 0 [:db_insert_placeholder_4] => [:db_insert_placeholder_5] => standard [:db_insert_placeholder_6] => 0 [:db_insert_placeholder_7] => page_manager [:db_insert_placeholder_8] => [:db_insert_placeholder_9] => H2 [:db_insert_placeholder_10] => 1 ) in drupal_write_record() (line 6888 of /Library/WebServer/Documents/www/jkl/includes/common.inc).

Any insight?

Answer 1

Looks like a known bug: unable to edit nodes with default panelizer state.

Try the patches in the above issue. Looks like it might be useful to chip in there with your issue also!

Thanks Chapabu. I've been through those, and tried merlinofchaos's #7 patch and get this in my apache error log : Fatal error: Declaration of PanelizerEntityNode::get_default_display() must be compatible with that of PanelizerEntityInterface::get_default_display() in /Library/WebServer/Documents/www/jkl/sites/all/modules/contrib/panelizer/plugins‌​/entity/PanelizerEntityNode.class.php on line 12 The other patches there don't work at all. :/
