How can I make up down buttons with a date picker widget ?
Buttons has to go up or down by one day.
I made a service to add remove days from a Initdate, but it is difficult to manage with mashup.
I cannot get a fully and well working system ...
The hard part here is the fact that you need to know if you pushed up or down and apply to the same date.
So I would take the date in the display and assign that to a Session Parameter
then I would create a day up day down service each button triggers their respective service and set that Server side to the Session Parameter
upon service invoke complete I would use GetSessionParameters to refresh the values client side and wire that back to the date display
