    ContentService SaveAndPublish Not Updating Cache for Media Picker Items?

    Hi,

    I've got a scenario where I can upload an image from the front end website which then gets allocated to a piece of content as below:

    IContent clubPage = ApplicationContext.Services.ContentService.GetPublishedVersion(club.Id);
clubPage.SetValue("clubLogo", image.Id);
ApplicationContext.Services.ContentService.SaveAndPublishWithStatus(clubPage);

    If I view the page in the Umbraco back office I can see that the media item has been allocated to it however if I then attempt to view the page on the website that uses that media item I get a

    String "nnnn" is not a valid udi

    exception thrown when attempting to work with the page's model property e.g.

    string logoUrl = clubHomePage.ClubLogo.Url;

    If I go back into the Umbraco Back Office and physically Save and Publish the page everything works fine but I can't rely on that as users of the site don't have access to the back office.

    Advice very much appreciated.

    Okay I've found out what I need to do to get this to work. I've had to change the code to:

    IContent clubPage = ApplicationContext.Services.ContentService.GetPublishedVersion(club.Id);
var udi = Udi.Create(Constants.UdiEntityType.Media, image.Key);
clubPage.SetValue("clubLogo", udi.ToString());
ApplicationContext.Services.ContentService.SaveAndPublishWithStatus(clubPage);

    Why? Well in v7.6.0 UDIs were introduced along with a whole bunch of "2" suffixed pickers and it appears as though the UDI needs to be used over the old Id when working with pickers.
