Hello,

I have made a MacroPropertyType that inherits a RadioButtonList. It installs fine and shows upp fine, but when i pres the "Ok" button to insert the macro in a template it gives me an javascript error:

"Umbraco.Controls.TreePicker' is null or not an object" in the function "saveTreepickerValue"

// hack for tree based macro parameter types
var picker = Umbraco.Controls.TreePicker.GetPickerById(controlId);

Anyone knows what could be wrong, should it not be able to use a radiobuttonlist?

I have a list of Images I want the user to choose from.
