HI,

i got some trouble with my preview. Maybe you can help me. First, the stacktrace:

at System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) 
at System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) 
at System.Linq.Enumerable.WhereSelectArrayIterator`2.MoveNext() 
at System.Linq.Buffer`1..ctor(IEnumerable`1 source) 
at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source) 
at Umbraco.Web.PropertyEditors.ValueConverters.MultipleMediaPickerPropertyConverter.ConvertDataToSource(PublishedPropertyType propertyType, Object source, Boolean preview) 
at Umbraco.Web.PublishedCache.XmlPublishedCache.XmlPublishedProperty.get_Value() 
at Umbraco.Web.PublishedPropertyExtension.GetValue[T](IPublishedProperty property, Boolean withDefaultValue, T defaultValue) at Umbraco.Web.PublishedContentModels.xxxxx.get_Image() 
at ASP._Page_Views_Partials_Grid_Editors_xxxxxxxx_cshtml.Execute()

This happens when i want to get the PropertyValue from a media picker field. On published view the image is rendered and no exception.

The RawData is a Guid at preview and on published view a id.

Any ideas why this happens?

Best Thobias

I am not really sure what kind of code you want to see, maybe this:

 <a href="@publication.ImageLink.Url" target="_blank">test </a>

and the generated method from "publication" type:

///<summary>
        /// Image Link
        ///</summary>
        [ImplementPropertyType("imageLink")]
        public IPublishedContent ImageLink
        {
            get { return this.GetPropertyValue<IPublishedContent>("imageLink"); }
        }

Does this help you?

Can you debug this code?

Only preview mode causes the exception?
