Hi,

i'm using BIRT 3.7 and i have this problem:

The following items have errors:

ReportDesign (id = 1):
+ The following visibility expression does not evaluate to a legal boolean value: null. (Element ID:1)

In my DataElement i have the following code at Visibility Property:

if ( row["d1-3"] < row["_DataInicial"]) {
reportContext.setGlobalVariable("_saldo", row["t1"]) ;
true;
}else{
reportContext.setGlobalVariable("_saldo", row["tm3"]) ;
false;
}

How can I solve this?
Thanks for help!
