I am having a problem. I have a field that would look something like this "test 1;Test 2;;;" where it holds 5 values. I understand it's bad design but this is some legacy stuff I'm trying to interface with. It will always be 5 values. I created 5 varibles of string type. var1,var2, and so on. var1 expression looks like this... ( $F{MaintOptionDesc}.split(";")[0] == null ? "BLANK" : "NOT BLANK" ) as long as the string is like this "test1;;;;" it works and doesn't error out. But if the string is ";;;;" it errors out. How can i modify this epression to handle no values.

I don't like how the output to csv handles titles and other bands in iReport. I was wondering if their is a way i can determind if the report is being dumped to a csv file or not and if it is being dumped as a csv file i want to remove certain bands. Is this possible? If it is a csv file, I don't want to print the title, page header, and footer. If it is not a csv file then i want to print them. is this possible with iReports?
