As mentioned in the preamble, by default all previously created types of vacations allow to request for only daily leaves after an upgrade to version 2.x. To allow users to request new type of leaves, administrator has to edit vacation type (1) and select proper type of vacation document (2). Type of vacation document is the property restricting users from requesting specific type of leave. For example, if type of vacation document is set to Daily or half-daily, users will not be able to request hourly leaves for the vacation type.
