Fixed for HEAD and FRAMEWORK_3.

Analysis looks correct.

Am trying to use an hourMinuteSecond variable for input and display 
only, by doing something like this in a form object:



     $this->addVariable(_("Start Time"), "start_time", 
'hourMinuteSecond', false);



In order to put a value in there for display have tried these options:



       $this->_vars->set('start_time', array("hour" => $hour, "minute" 
=> $minute, "second" => $second));



Which works when the form is active (input) but not inactive (display 
only). In display only, the value is not shown (just a blank space 
appears).



Have also tried this:



       $this->_vars->set("start_time[hour]", $hour);

       $this->_vars->set("start_time[minute]", $minute);

       $this->_vars->set("start_time[second]", $second);



With the same result.



The only way to get something to appear in display only (inactive 
form) is do to this:



       $this->_vars->set($timevar, "$hour:$minute:second");



But then the value is not shown when the form is active for input from 
the user.



I believe the last option I show is incorrect and the display of the 
first two is broken because there should be a custom 
_renderVarDisplay_hourMinuteSecond functon.
