Report works in iReport but fails in JasperServer

[jslater]

Hi all

Software Versions

iReport : 3.7.0 and JasperServer : 3.7.0

 

Issue

The report uses a List object to provide the user with a multi-select parameter which is then used in a query.

Work perfectly in iReports.

But when published in JasperServer provides the following error

"com.jaspersoft.jasperserver.api.JSExceptionWrapper: Unknown column name : <column name>"

 

Attempted

After searching the forums replaced all occurences of the following file, jasperreports-3.7.0.1.jar with jasperreports-3.7.1.1.jar (taken from JS 3.7.1).

Unfortunately no success :-(

 

Please could someone be kind enough to provide a helping hand as I am totally lost and helpless now.

Thanks in advance

John
