clearSessionVar
The clearSessionVar
method deletes a specified session variable, if it exists.
NOTE: If you delete a session variable, and the current conversation task has a requirement to set the variable, the conversation task asks the user to provide a new value for the variable. If the current conversation task does not have a requirement to set the deleted variable, and you use the variable in a template, the conversation task returns a placeholder string (?)
.
To ensure that you do not get empty placeholders in your responses, OpenText recommends that you include a requirement for all session variables that you want to use in a response. If the session variable has been set in an earlier task, the conversation task does not ask for it again.
