Problem Symptoms:
Adding the token validation with "TOKEN-VALIDATION=Y" in $alephe_tab/tab100 and updating the required html-files with the $9900 place holder as hidden parameter does not bring the expected result but runs into error message "CSRF Violation occurred. Please re-login into the system." when trying to delete records from My e-shelf or when trying to use the *Renew All* functionality.

Configuration

Resolution:
In some of the tables which should be enhanced by a line like ...
<input type=hidden name="token_id" value=$9900>
... according to documentation the line is missing.
