Error while trying to export from JasperViewer

[SteveF]

Hello, when trying to export a report to xls i get that error:

 

Code:

java.lang.reflect.InvocationTargetException
	at com.jasperassistant.designer.viewer.actions.AbstractExportAction$1.run(AbstractExportAction.java:135)
	at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:101)
Caused by: java.lang.NoSuchFieldError: IS_ONE_PAGE_PER_SHEET
	at com.jasperassistant.designer.viewer.actions.ExportAsSingleXlsAction.exportWithProgress(ExportAsSingleXlsAction.java:71)
	at com.jasperassistant.designer.viewer.actions.AbstractExportAction$1.run(AbstractExportAction.java:132)
	... 1 more

The export to other formats works fine.

Could you please help me?

You're probably using JasperAssistant with an unsupported JasperReports version. You might find more information about this on JasperAssistant's forum.
