Hi

I am using iReports 4.1.1 and JasperServer CE 4.1.0

I have a report which works fine in iReports, but when I upload it to the server and run the report I get:

    java.lang.Exception: 1 - Errors were encountered when compiling report expressions class file:
1. Cannot cast from Timestamp to String
value = (java.lang.String)(((java.sql.Timestamp)field_TRIPDATETIME.getValue())); //$JR_EXPR_ID=50$

etc etc

I can't understand why iReports would run fine, but the server not.

I understand its a coversions problem, but not why when iReports runs without error.

Thanks
