* Note:
* 1. When adressing variables from submit containing
* Prefix_Special as part of their name use
* $event->getPrefixSpecial(true) instead of
* $event->Prefix_Special as usual. This is due PHP
* is converting "." symbols in variable names during
* submit info "_". $event->getPrefixSpecial optional
* 1st parameter returns correct corrent Prefix_Special
* for variables beeing submitted such way (e.g. variable
* name that will be converted by PHP: "users.read_only_id"
* will be submitted as "users_read_only_id".
*
* 2. When using $this->Application-LinkVar on variables submitted
* from form which contain $Prefix_Special then note 1st item. Example:
* LinkVar($event->getPrefixSpecial(true).'_varname',$event->Prefix_Special.'_varname')
