Cannot set the value of an ACCESS::session variable with a leading hyphen.
Cannot use hyphen in session variable value. The system posts and error message similar to the following: err tmm3[12741]: 01220001:3: TCL error: /Common/pass <ACCESS_POLICY_AGENT_EVENT> - bad option name (line 1)setting variable var_name for sid (null) failed (line 1)Illegal argument (line 1) (line 1) invoked from within "ACCESS::session data set var_name "-foo""
Using a leading hyphen for the value of the session variable, for example: ACCESS::session set data var_name -value.
This issue has no workaround at this time.
In this release, an extra parameter, made up of two dashes (--), was added. When -- is inserted before a value, the value can start with a hyphen; for example, "ACCESS::session set data var_name -- -value".
