MultinodeTreePicker behaviour changed in 0.9.x #179

Closed JimBobSquarePants closed 8 years ago

In previous versions assigning a DittoPickerConverter to a MyClass would always return an IEnumberable<MyClass> whether one or many items were picked.

In 0.9.0 when a single item is picked the following exception is thrown.

Additional information: Unable to cast object of type 'System.String[]' to type 'System.Collections.Generic.IEnumerable`1[MyClass]'.

Umbraco Version 7.4.3

Just added a single to multiple test and it's working. Beginning to suspect this is an Umbraco 7.4.* thing

So it turns out that the difference was that when searching for attributes on type declarations we were no longer searching the type parameters within generic types. This meant pickers were no longer working without having both UmbracoProperty and UmbracoPicker defined on the property.
