'No model set' after choosing Create new Content for the datasource of the rendering

Question

We're experiencing the 'No model set' error message in the markup where we are calling the Glass Editable method. This is present after adding the rendering via the Experience Editor and choosing to 'Create New Content' for the datasource.

No model set

at Glass.Mapper.Sc.GlassHtml.MakeEditable[T](Expression1 field, Expression1 standardOutput, T model, Object parameters, Context context, Database database, TextWriter writer) in ~\Glass.Mapper.Sc\GlassHtml.cs:line 565

I'm assuming it's because after selecting to create the new Item the rendering is reloaded but before the Item has finished being created hence the Model not being set.

The code isn't particularly fancy

View

@if (Html.Glass().IsInEditingMode || !string.IsNullOrEmpty(Model.HeadingTitle))
{
    <h3>@Html.Glass().Editable(Model, x => x.HeadingTitle)</h3>
}
<div class="sitecore-content">
    @Html.Glass().Editable(Model, x => x.Information, x => Html.Sitecore().Field(I_BaseInformationConstants.InformationFieldName).ToString())
</div>

Controller

public ActionResult TextBlock()
{
    // GetLayoutItem method from GlassController
    var basicContent = GetLayoutItem<ITextBlock>();

    return View("/Views/Shared/Components/TextBlocks/TextBlock.cshtml", basicContent);
}

I can wrap the code in a Null check to prevent the error but then the Editable aren't present to enter content. Anyone address this problem before?

Answer 1

As you said that it looks like it gets the web database not the master. If you post the whole GetLayoutItem<T>() methond then I can add a more precise answer, but it looks like that something wrong in that method.

Possible reason

I assume that you initialize somewhere an ISitecoreContext object and you use the GetItem<T>() method of ISitecoreContext. Could be that you initialize it as a Singleton if you are using IOC. But it should be at least LifestylePerWebRequest because if you call the new SitecoreContext() without parameters then it's using the context database. So if it's a Singleton then it uses always that database which was the context initially.

These are just assumptions but could be helpful if you have this case.
