So next question, along similar lines. Having looked at 
DBIx::Class::HTMLWidget, I'm a bit confused by its fill_widget() method. 
This sets values using $widget->element()->value() and goes as far as to 
show some example Catalyst controller code in the synopsis.

But none of the example TT code I've seen works on the HTML::Widget 
object, it all uses the HTML::Widget::Result object generated by 
$widget->process(). Whether or not you supply it a query, process() 
doesn't appear to preserve any element values. Calling process() after 
fill_widget() therefore appears to lose all the values stored by 
fill_widget().

It would be possible to create a TT template that iterates through the 
elements in a HTML::Widget object, but IMO it would make a lot more 
sense if calling process() without a query preserved all the values 
stored on individual elements. That way you'd only need a single template.
