I use version 0.17.1 and recognized that I can create object without common name. I check the config option "List source: object, for which common name should be set" and the object type is listed there. If you search for an object without common name but with barcode you receive a strange error message. To reproduce follow this steps: 1. Add network switch without common name but with barcode (e.g. 123456) 2. Search for barcode (123456) 3. You get an error message like this: SQL query 'SELECT tag_id, RackObject.id, RackObject.name, RackObject.label, RackObject.barcode, RackObject.asset_no, RackObject.objtype_id, (select rack_id from RackSpace where object_id = id order by rack_id asc limit 1) as rack_id, (select name from Rack where id = rack_id) as Rack_name, (select row_id from Rack where id = rack_id) as row_id, (select name from RackRow where id = row_id) as Row_name, (select dict_value from Dictionary where dict_key = objtype_id) as objtype_name, RackObject.has_problems, RackObject.comment FROM RackObject LEFT JOIN TagStorage on entity_realm = 'object' and entity_id = RackObject.id WHERE RackObject.id = 963 ORDER BY tag_id' failed in useSelectBlade with error 2014 (Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.) Go back or try starting from index page. Fatal error: Call to a member function fetch() on a non-object in /var/www/vhosts/racktables.org/demo/0.17.1/inc/database.php on line 373 Workaround: 1. Note the RackObject ID from the SQL query 2. Open the following URL in your webbrowser: https://your.racktable.installation/?page=object&object_id={ID} (replace {ID} with the RackObject ID from step 1) 3. Enter a common name 4. Search for the barcode (123456) Now everything works again. I think the option "List source: object, for which common name should be set" should be "List source: object, for which common name MUST be set" an those types must be prechecked before you can add them. Hope I could help. Killsystem
