Extend Config Parameter option list (DialogConfigParmOption)


I'm trying to extend the list of config parameter options for an existing (non-custom) parameter, I added a entry in DialogConfigParmOption and added the FK (UID_ConfigParameter) of the parameter I want this option being available at. Even after compiling and restarting the Designer, the option is not displayed at the config parameter's value list.

Am I missing something at this point ? The only difference between the existing options and the one created by me that I can see is: The existing parameter option's UID start with TSB, the one created by me starts with CCC.
