Currently, if the user saves the auto-install.xml record at the end of the installation in the FinishPanel, there are saved variable entries for all fields of a UserInputPanel, regardless of whether they are presented to the user depending on a condition (e.g. whether they are displayed or invisible).
For invisible fields there are use empty values: ""
This is not correct. The right record of an installation for a UserInputPanel should contain just variables of those fields which are really displayed and user-editable.
