Add "all values" in an input multi selected input control

[pioppogatto]

I have a report in iReport 4.7.1 with a multi-selected input control, java.util.Collection mandatory, and the result of the query in JasperServer gives a lot of values. I'd like to insert in my input control a Check Box "All values" in order to select all the values and not selct them one by one.

Example: code for input_control

select A from Tab returns values: a, b, c, d, e .....

 

code for my query report

select * from tab where $X{IN, field, input_control}

 

Is it possible?

FYI - if input_control is null, $X{IN, field, input_control} will return all values.
