Editing class properties doesn't affect nodes


I’m following this tutorial : Daniel Walz - Build Your Juce UI's easily with Plug-in GUI Magic (Pt 1 of 2) - YouTube and at 16:40 there’s an example of editing a Type’s properties to change the look of all nodes of that type. This doesn’t work for me. When I change the type’s properties everything stays the same. I tried saving the xml and refreshing but that didn’t do anything.

On a related note, when I try to change the class of a view node, the plugin crashes.

Any help would be greatly appreciated.

Ps: I saw another post about this; I don’t have an extra MagicProcessorState defined in my project.
