Hello,

I am working on a staging site that is running, and want to update the way a partial view is using the model of a Data Type.

For instance the (archetype) data type previously allowed the user to select one image and I want to allow the user to select two images which then should be accessible from a new or updated partial view.

I added a second media picker property to the data type and that is visible to the backoffice user. However when I write a block in the partial view that tries to access the data the user selected the site will produce a 500 error whenever that partial is loaded.

Here I added a media picker property named sImage to the DataType that already had a media picker named Image. And tried to access it in a partial like so:

    @if (Model.Image.IsSet())
    {
        <div class="feature-img-right">
            <img src="@Model.Image.Url" alt="@Model.Image.Alt" />
        </div>
    }

    @if (Model.sImage.IsSet())
    {
        <div class="new-img">
            <img src="@Model.sImage.Url" alt="@Model.sImage.Alt" />
        </div>
    }

I am guessing this is because changing the Data Type properties etc doesn't actually change the model? Is there some way to update the model or a trick to access new properties of a Data Type without updating the model? I might be misunderstanding the relationship between Data Types and the models.

Thanks for any help!
