    Unable to get value for media property 'umbracoFile' after saving media

    Hi all,

    Has anyone else come across a problem in Umbraco 7.5.3 where you can no longer access the umbracoFile property of an image after saving the media?

    If I upload an image I can access the URL as expected using:

    var media = Umbraco.TypedMedia(1510);
var url = media.GetPropertyValue<string>("umbracoFile");

    But, if I then save the media item via the backend (perhaps to replace the image etc), I can no longer get the URL by querying for the umbracoFile property as I get an exception:

    [ArgumentNullException: Value cannot be null.
Parameter name: source]
   System.Linq.Enumerable.Any(IEnumerable`1 source) +4356218
   Umbraco.Web.Models.ImageCropDataSet.ToString() +18
   Umbraco.Core.ObjectExtensions.TryConvertTo(Object input, Type destinationType) +358
   Umbraco.Core.ObjectExtensions.TryConvertTo(Object input) +71
   Umbraco.Web.PublishedPropertyExtension.GetValue(IPublishedProperty property, Boolean withDefaultValue, T defaultValue) +171
   Umbraco.Web.PublishedContentExtensions.GetPropertyValue(IPublishedContent content, String alias, Boolean recurse, Boolean withDefaultValue, T defaultValue) +82
   Umbraco.Web.PublishedContentExtensions.GetPropertyValue(IPublishedContent content, String alias) +59

    Has anyone experienced the same problem? Is this a bug?

    Thanks, Justin

    Hi Justin,

    What version of Umbraco are you using?

    Try to use this syntax:

    var url = media.Url;

    Thanks,

    Alex

    Hi Alex,

    I'm using Umbraco 7.5.3.

    Yes, it does work when accessing the media.Url property. I just find it odd that saving the media item can cause different behaviour when getting the URL using the umbracoFile value directly.

    Debugging through, if I use this code it returns an ImageCropDataSet:

    var url = media.GetPropertyValue("umbracoFile");

    Before saving the media item, the ImageCropDataSet has:

    Crops = 0
FocusPoint = null

    After saving the media it has: 

    Crops = null
FocusPoint = 0.5/0.5

    So, the ToString() on the ImageCropDataSet is not handling the fact that the Crops is null and throwing the exception.

    At least I have a workaround but just wondered if it was a bug or intended behaviour?

    Thanks, Justin
