ICustomTypeConvertor not supported?

Questions / suggestions / bugs

Hi

I've got a site running uSiteBuilder 1.2 that utilises ICustomTypeConvertor quite heavily. After installing this package (thus now using the forked version of uSiteBuilder) these are no longer working. I'm getting exceptions trying to convert from strings to my custom types.

Is ICustomTypeConvertor not supported in this version of uSiteBuilder?

Have you got an example of the error you're getting?

I have changed the way the CustomTypeConvertors were working, they used to be held in a dictionary that was keyed on the return type but I sometimes had different convertors returning the same type (like List<string> say) so this approach wouldn't work.

I now allow them to be configured on the doc type property itself, like below.

I can have a look into the error you are getting as you should still be able to do both ways I guess.

        [DocumentTypeProperty(
            UmbracoPropertyType.Other,
            OtherTypeName = "Energy Item Selector",
            Name = "Energy Features Third Row",
            Description = "Select the featured items for the third Energy feature row",
            Tab = "Energy",
            CustomTypeConverter = typeof(MultiNodeTreePickerConverter),
            Mandatory = false)]
        public List EnergyFeatureSet3 { get; set; }

Specifying the CustomTypeConvertor seems to fix the issue.

For info the error is:

Server Error in '/' Application.
