How to display a line from result of subreport

[johann60280]

Hello everybody!!

 

I have a problem on Ireport. I try to display a line  from a result of subreport. So I have a subreport who contains some result (or not). I use a parameter in this subreport who called "Return values". I affect this parameter in a variable called "affiche". So this variable contains "1" if there is one result in the subreport or "0" if there is nany result. So I try to hide a line who are next to the subreport if my variable contain "0".

This is my condition in line (on a parameter "Print When Expression"):

$V{affiche} != "0" ? Boolean.TRUE : Boolean.FALSE

 

But unfortunately it doesn't work. I put an image to show mu problem.

 

I hope my case is clear but if you want more explanation I will can give you. Thank you to help me :)

If your variable is of type java.lang.String, use

!$V{affiche}.equals("0")

as print when expression.

If your variable is of type java.lang.Integer, use

$V{affiche} != 0

Oh thank you for your help!! Yes it work but not completely..

Indeed my variable is of type java.lang.integer. I use what you give me with a modification:

$V{affiche}.intValue() != 0 ?
Boolean.TRUE
: Boolean.FALSE

But the line is misssing when my variable return not 0. Can you tell me why ?
