Hello,
I get an error using a report parameter (type Date) in a computed column
of a dataset. If I use following expression: params["xyz"].getYear();
I'll get the following error: "The data type of computed column "xyz" is
java.lang.Integer, but one of its value is "null", which cannot be
converted to java.lang.Integer". Anyone know how to solve this problem?
The report parameter has a default value.
Thanks for help!

Helmut,
Can you post your report?
The error you are getting usually happens when one of the data set
values is null and it is used in a calculation.
