When the BIS_fnc_exportGUIBaseClasses function is used to export the base classes for the Eden Editor, the order of the class definitions are incorrect and cause errors when the exported classes are used in the provided order. There are multiple issues with the order, however one of the main issues in the order include ctrlDefault being defined after other classes which inherit it are. There are several classes which are exported either too early or too late, causing issues with inheritance. I can provide a full list if need be however it may be easier on your end to find that out.
