Experts,
We are using BIRT4.3.1 version,. We have upgrade BIRT 2.1.1 version reports into new version. In the older version we have date comparison in the columns. But it is not working in the new version. Below is the details
FYI.. We are using XML datasource.
We have added these two columns as computed columns in the dataset.
Date1
if( row["DUE_DATE"] != null ){
importPackage( Packages.java.text );
var sdf = new SimpleDateFormat("dd-MMM-yy");
sdf.parse(row["DUE_DATE"] );
}
Date2.
if( row["STA_DATE"] != null ){
importPackage( Packages.java.text );
var sdf = new SimpleDateFormat("dd-MMM-yy");
sdf.parse(row["STA_DATE"]);
}
else{
new Date();
}
Comparison column...
DateTimeSpan.days(row["ED"], row["SD"])
But we are getting error message as follows. Please assist me.
T

+ Fail to compute value for computed column "ED".
