returns in an NullReferenceException. The same happens if I will access the Value() property:
var test = element.GetProperty("iconTextBoxList");
var test2 = test.HasValue();
var test3 = test.GetSourceValue(); // => contains the JSON-String with correct Value
var test4 = test.Value(); // => NullReferenceException
var iconTextBoxList = element.Value<IEnumerable<IPublishedElement>>( "iconTextBoxList" ); // => NullReferenceException
I have already republish the content node, rebuild the examine indexes, rebuild the database cache and reload the memory cache without luck.
Anyone knows this issue and has a solution to solve this?
Just to let you know I came across this today - a bug present in 8.18.8 (current v8 at the time of writing).
I have a possible workaround which I'll share further down for anyone else stuck on this in the meantime!
For me, Nested Content in Umbraco 8 generally behaves, when this bug bites it will always return null due to an error parsing the nested content data in PureLiveModelFactory.CreateModelList(...) - hence there is no way to test for it since any call to .Value(...) even without casting will result in this exception
The full stacktrace for me looks like:
Umbraco.ModelsBuilder.Umbraco.PureLiveModelFactory.CreateModelList(String alias)
at Umbraco.Web.PropertyEditors.ValueConverters.NestedContentManyValueConverter.ConvertIntermediateToObject(IPublishedElement owner, IPublishedPropertyType propertyType, PropertyCacheLevel referenceCacheLevel, Object inter, Boolean preview)
at Umbraco.Core.Models.PublishedContent.PublishedPropertyType.ConvertInterToObject(IPublishedElement owner, PropertyCacheLevel referenceCacheLevel, Object inter, Boolean preview)
at Umbraco.Web.PublishedCache.NuCache.Property.GetValue(String culture, String segment)
at Umbraco.Web.PublishedContentExtensions.Value(IPublishedContent content, String alias, String culture, String segment, Fallback fallback, Object defaultValue)
at ASP.PageViewslistSectioncshtml.Execute() in \My\Project\Views\SomeView.cshtml line 123
Workaround that worked for me!
Since this is a bug (only) within the PureLiveModelFactory.CreateModelList(...) method you can simply change the Web.config AppSettings to use anything other than "PureLive" (I updated mine to be "AppData" since I had no particular need for any particular Models Builder type on this project - thankfully!) and the same code with the same data will work. Hopefully your project allows this.
I've not had a chance to debug the code at the moment as I've got a few things on, but thought I'd share what I found in my case in case it's helpful.
I suspect there can become a secnario where the parsing of data can throw an unhandled exception within the CreateModelList(...) method of the PureLive Models Factory
NullReferenceException with NestedContent (no Value(), but existing SourceValue())
Hello,
I have the same strange Issue in Umbraco v8.18.1 with NestedContent like described here:
https://github.com/umbraco/Umbraco-CMS/issues/7364
HasValue() returns true and the Property "SourceValue()" contains the correct JSON-String with the complete value.
But
returns in an NullReferenceException. The same happens if I will access the Value() property:
I have already republish the content node, rebuild the examine indexes, rebuild the database cache and reload the memory cache without luck.
Anyone knows this issue and has a solution to solve this?
Best, Sören
Hey, I have the same issue. Found any solution or reason for this?
