I have created a custom property and it stares a json object.

It worked initially when the propertyEditorSchemaAlias was a Umbraco.Plain.Json

But now trying to add the DataValueEditor and validation as per the my suggestions example but this is for a string.

Cant find the documentation to support other value types.

Code is as below

namespace Umbraco.Docs.PropertyEditors;

[DataEditor("IBD.Additional.Classes", ValueEditorIsReusable = true)] public class IBDAdditionalClassesDataEditor : DataEditor { public IBDAdditionalClassesDataEditor(IDataValueEditorFactory dataValueEditorFactory) : base(dataValueEditorFactory) { }

protected override IDataValueEditor CreateValueEditor()
    => DataValueEditorFactory.Create<IBDAdditionalClassesDataValueEditor>(Attribute!);

}

public class IBDAdditionalClassesDataValueEditor : DataValueEditor
{
    public IBDAdditionalClassesDataValueEditor(
        IShortStringHelper shortStringHelper,
        IJsonSerializer jsonSerializer,
        IIOHelper ioHelper,
        DataEditorAttribute attribute)
        : base(shortStringHelper, jsonSerializer, ioHelper, attribute)
        => Validators.Add(new IBDAdditionalClassesValueValidator());
}

public class IBDAdditionalClassesValueValidator : IValueValidator
{
    public IEnumerable<ValidationResult> Validate(object? value, string? valueType, object? dataTypeConfiguration)
    {
        return (value is System.Text.Json.JsonDocument
            && dataTypeConfiguration is not Dictionary<string, object?> dataTypeConfigurationValues)
            ? []
            : [new ValidationResult($"Not Valid value")];
    }
}

Not sure if the validation is correct?

Error that is logged is this when saving and publishing the document.

I think some how I need the IBD.Additional.Classes to be stored in the textValue column for the table rather than the varCharString column.

or make IBD.Additional.Classes the equivalent of Umbraco.Plain.JSon
