Grails "Unparseable Date" Error <p>I've seen some Unparseable Date errors on here before, but mine doesn't seem to make any sense. I'm uploading a CSV file, which is going to be displayed in a table on a webpage (that much I know and is easy) and I'm trying to find a way to take the date in a cell and convert it from it's native string format to a date.</p> <p>Here's the code:</p> <pre><code> def line = f.inputStream.toCsvReader(['skipLines':1]).eachLine{fields -&gt; List list = new List() list.item = fields[0].trim() String checkedOut = fields[1].trim() String returned = fields[2].trim() Date c = Date.parse('E MM/dd/yy', checkedOut) Date r = Date.parse('E MM/dd/yy', returned) list.lastCheckedOut = c list.lastReturned = r list.checkedOutBy = fields[4].trim() list.save flush: true return } </code></pre> <p>Here's the stacktrace </p> <pre><code>Error 2015-08-21 16:13:38,936 [http-bio-8080-exec-7] ERROR errors.GrailsExceptionResolver - ParseException occurred when processing request: [POST] /inventory/list/upload - parameters: upload: Upload Unparseable date: "9/22/94".
