Not sure if this is a bug or I have made a mess of something somewhere. So appologies if it is down to something daft I have done!

I have a Datepicker in a document type that is giving me a yellow screen of death with the error "String was not recognized as a valid DateTime."when I attempt to get a preview of a document using the preview button in umbraco.

The problem does not occur if I view the live published page.

I am using an umbraco:Item tag in my template to pull the date from the doc type. From playing round with it, the problem starts happening when I set the property formatAsDate="true" on the umbraco:Item tag.

I got around it by creating an .net usercontrol to do the date formatting and calling it from an umbraco macro.

So I am just wondering if am just missing something obvious, or there is problem using the formatAsDate property in conjunction with the document preview?

Thanks

Jim
