Create new Nodes/Entities for Reference Fields on the fly

For the Entity Reference (http://drupal.org/project/entityreference) there exist two modules, which make it possible to create the nodes you want to reference on the fly.

Those are

• http://drupal.org/project/entityconnect
• http://drupal.org/project/references_dialog

At the moment there is a bug in reference dialog with multivalue fields. See http://drupal.org/node/1537136 and http://drupal.org/node/1504498
