Hi! I'm trying to concatenate 2 fields in a single box. The box have the "Blank when null" property checked, the problem is that when the box receive any of the fields with data, and the second field in "null" it shows the null text instead the blank space. I though about fixing it by Java code, changing the null for a blank space like " " but I would like to know if there's a way to do it with iReport 1.2.5. Thanks!
