When used in a field of field_collection with embedded widget, $form_state contains only the fields of the node, not the fields in field_collection. I found this by catching these PHP notices and seeing that $form_state doesn't contain the needed field:

Notice: Undefined index: field_protein_ref in entityreference_view_widget_validate() (line 478 of /srv/drupal/sites/all/modules/entityreference_view_widget/entityreference_view_widget.module).
Notice: Undefined index: und in entityreference_view_widget_validate() (line 479 of /srv/drupal/sites/all/modules/entityreference_view_widget/entityreference_view_widget.module).

Same problem here:

Notice: Undefined index: #fields in entityreference_view_widget_validate() (line 474 of /var/www/cdt/sites/all/modules/entityreference_view_widget/entityreference_view_widget.module).
Notice: Undefined index: field_characters in entityreference_view_widget_validate() (line 475 of /var/www/cdt/sites/all/modules/entityreference_view_widget/entityreference_view_widget.module).

Is the any workaround available at the moment?

regards!
