Hello, I've just reported a new Jira for excel export.
Jira 3834
I think the problem is in
JXLHelper.java 644
case date: return new DateTime(column, row, (Date) data, cellFormat);
I think is the cast to (Date) that throws exception.
Should I filter in the model?
java.lang.ClassCastException: java.lang.String

at org.jboss.seam.excel.jxl.JXLExcelWorkbook.addItem(JXLExcelWorkbook.java:514)
at org.jboss.seam.excel.ui.UIColumn.encodeBegin(UIColumn.java:80)
I've commented on the fix.
