[iReport Designer Not formating the Date correctly]

Check your field datatype in "report query" window (should be java.sql.Date). Try to use below expression, it is working for me :

new SimpleDateFormat("dd/MM/yyyy").format($F{FullDateAlternateKey})

[How to pass default value to dashboard parameters(input controls) ?]

This works only for the day when the item is dragged to the dashboard. I did this some time back and it showed correct day. When I log in into my dashboard today, it still has the previous date.

 

Lets take an example to understand this better. I have created this dashboard on '2014-04-01' date, it was working fine for '2014-03-02' (From) and '2014-04-01' (To) date range. Now when we try to run dashboard, it is suppose to show result for '2014-03-17' (From) and'2014-04-16' (To), but instead of doing that we are getting results for '2014-03-02' (From) and '2014-04-01' (To) date range.
