    GetPropertyValue error on image after upgrade

    After upgrading from 7.6.0 to 7.14.0, I am now getting an "Object reference not set to an instance" error when trying to get an ImagePicker property.

            @if (Model.Content.HasValue("bannerImage"))
        {
            var temp = Model.Content.GetPropertyValue("bannerImage");
            <img src="@Umbraco.TypedMedia(Model.Content.GetPropertyValue("bannerImage")).Url" />
        }

    I tried changing EnablePropertyValueConverters to false, and that seemed to fix this particular code, but it broke GetPropertyValue calls for other properties. Any suggestions as to what might be causing this and how to fix it?

    Hi Jose

    With PropertyValueConverters enabled then you should be able to do this:

     @if (Model.Content.HasValue("bannerImage"))
        {
            var bannerImage = Model.Content.GetPropertyValue<IPublishedContent>("bannerImage");
            <img src="@bannerImage.Url" />
        }

    Essentially the property value converter for a single media picker will do the whole Umbraco.TypedMedia step for you...

    Regards

    Marc

    Thanks Marc. The error occurs at GetPropertyValue. This line fails as well.

    var bannerImage = Model.Content.GetPropertyValue<IPublishedContent>("bannerImage");

    Hi Jose

    Have you rebuilt your Examine InternalIndex since the upgrade?

    and if you find the image in the backoffice media section and 'save' it again - does it work?

    regards

    Thanks again, Marc. I hit save on the image's media record. I also tried rebuilding the index by deleting the files in Internal\Index. Neither of these actions seemed to make a difference.

    Hi Jose

    Is it a single Media Picker or Multiple Media Picker?

    If multiple then...

    var bannerImage = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("bannerImage").FirstOrDefault();

    also does it blow up on 

    var mediaId = Model.Content.GetPropertyValue<int>("bannerImage");

    ?

    regards

    Marc

    It is a single Umbraco.MediaPicker (not MediaPicker2). It blows up with GetPropertyValue<int> as well.
