我想克隆一个Canvas对象,它包含一个带有几个Geometry形状的Degrafa Surface.

我尝试了天真的方法:

return ObjectUtil.copy(graph_area) as Canvas;

导致错误:

TypeError: Error #1034: Type Coercion failed: cannot convert Object@63b1b51 to com.degrafa.geometry.Geometry.
TypeError: Error #1034: Type Coercion failed: cannot convert Object@63b1039 to com.degrafa.geometry.Geometry.
TypeError: Error #1009: Cannot access a property or method of a null object reference.
