Re: Suggestion for improved range form control

Greetings Andrew, are you suggesting that such a control should bind to 
two items of instance data, such as <ealiestDate> and <latestDate> with a 
constraint that latestDate >= earliestDate, or to a single item and its 
minInclusive & maxInclusive constraints. We already support the latter.

Regards, Roland

I have been playing with the range form control and would like to suggest 
an
improvement to it or a complementary form control.

What I have in mind would be like a range form control but with two
interactive indicators - one to correspond to the minimum allowed/chosen
value and the other to the maximum allowed/chosen value.

I can think of several scenarios where this type of functionality might be
useful. For example:
1. Hotel booking - enter the start date (on a calendar?) corresponding to 
the
minimum chosen value and the end (of stay) date corresponding to a maximum
chosen value
2. A delivery of goods scenario. A minimum time of 07:00 (say) and a 
maximum
time of 21:00 (say) might be offered for delivery. The purchaser of goods
could indicate the time window within the seller-specified range when
delivery might suit them. In this case specifying a time might involve
dragging two sliders on a scale.

I am sure there must be other use cases but these should be sufficient for
others to get some feel for what I am suggesting so they can ponder 
whether
there is any value in the suggestion.
