Using Umbraco And Getting Started

Umbraco 9

I am getting an error when trying to create a block list data type programmatically.

{"ExceptionMessage":"Value of type BlockListConfiguration cannot be a configuration for editor Umbraco.BlockList, expecting. (Parameter 'value')"

The issue is when I am trying to set the configuration.

Please can you help me work out where I am going wrong?

Here is my code:

public void CreateDataType(string name)
{
    var newDataType = new DataType(
        new DataEditor(_dataValueEditorFactory)
        {
            Alias = "Umbraco.BlockList"
        }, _configurationEditorJsonSerializer)
    {
        Name = name,
        Configuration = new BlockListConfiguration
        {
            Blocks = new[]
            {
                new BlockListConfiguration.BlockConfiguration
                {
                    ContentElementTypeKey = new Guid("08e05150-1fe7-4810-96d2-cc0b9fd77a40"),
                    SettingsElementTypeKey = new Guid("55876948-ac8b-440f-bbca-19ac2bb18189"),
                    Label = "{{ !$title || $title == '' ? 'Test ' + $index : $title }}",
                    EditorSize = "medium",
                    ForceHideContentEditorInOverlay = false,
                    Stylesheet = "",
                    View = "",
                    IconColor = "#ffffff",
                    BackgroundColor = "#1b264f"
                },
            },
            MaxPropertyWidth = "100%",
            UseSingleBlockMode = false,
            UseLiveEditing = false,
            UseInlineEditingAsDefault = false,
            ValidationLimit = new BlockListConfiguration.NumberRange()
            {
                Min = 0,
                Max = 10
            }
        }
    };

    _dataTypeService.Save(newDataType);
}

Kind regards

Paul

Hi Paul,

that is really weird. I get the same error when setting the configuration in the way you describe.

I tried a couple of things and when I saved the DataType first (without the configuration) and set the configuration afterward (with the same values), the configuration is being set correctly. (below ugly/verbose code used for testing purposes)
```
var config = new BlockListConfiguration{...}
_dataTypeService.Save(newDataType);
var testType = _dataTypeService.GetDataType(name);
testType.Configuration = config;
_dataTypeService.Save(testType);
```
I hope someone else has some good insights on why it does not work when constructing it from scratch.

Hi

I got it working. My friends Anders and Callum helped me in the MVP slack group.

I’ll update this post later with the solution.

Thanks

Paul
