I'm studying iReport Design and I started using Connection at my fillReport. Until then, it's ok. The problem is that, now, I'm using Collection, with the commands: List<Sales> sales = new SalesDAO().getSalesByDate( new SimpleDateFormat("yyyyMMdd").parse("20180101"), new SimpleDateFormat("yyyyMMdd").parse("20180131") );JRDataSource dataSource = new JRBeanCollectionDataSource(sales); In those way, when I try execute, it's show me the following error:

I'm studying the iReport Design report tool and, when I tried convert a String object to Date, I received the message: Error filling print... java.util.Date cannot be cast to java.lang.String[/code]I tried convert it using: new SimpleDateFormat("yyyyMMdd").parse($F{date})[/code]$F{date} is the String that I get from the query. I try convert it in the Pattern Expr. of Text Field Properties of the $F{date}. This don't work with Expression Class java.land.String and don't work with java.util.Date.
