I have a tag plugin with a sorted basearray and everything was ok, until I implemented CopyTo().
Now I am getting "error C2248: 'maxon::SortedArray<MYSELF,ARRAY>::operator =' : cannot access private member declared in class 'maxon::SortedArray<MYSELF,ARRAY>' c:\program files\maxon\cinema 4d r16\plugins oggle visibility development\source oggle visibility.cpp 10 1 Toggle Visibility"

What to do?
I read other posts about this issue, but I did not see a solution.

struct MySortedIntegerArray : public maxon::SortedArray<MySortedIntegerArray, maxon::BaseArray<Int> >
	// your sorted array must implement a LessThan() method
	static inline maxon::Bool LessThan(Int a, Int b)	{ return a < b; }
class ToggleVisibilityC : public TagData
	MySortedIntegerArray switchFramesList;		//is automatically sorted.
	Int32 switchFramesStartOnOff;
	virtual Bool Init(GeListNode* node);
	virtual EXECUTIONRESULT Execute(BaseTag* tag, BaseDocument* doc, BaseObject* op, BaseThread* bt, Int32 priority, EXECUTIONFLAGS flags);
	virtual Bool GetDDescription(GeListNode* node, Description* description, DESCFLAGS_DESC& flags);
	virtual Bool Message(GeListNode* node, Int32 type, void* data);
	virtual Bool CopyTo(NodeData* dest, GeListNode* snode, GeListNode* dnode, COPYFLAGS flags, AliasTrans* trn);
Bool ToggleVisibilityC::CopyTo(NodeData* dest, GeListNode* snode, GeListNode* dnode, COPYFLAGS flags, AliasTrans* trn)
	((ToggleVisibilityC* )dest)->switchFramesList = switchFramesList;		// <== Error
	((ToggleVisibilityC* )dest)->switchFramesStartOnOff = switchFramesStartOnOff;
	return NodeData::CopyTo(dest, snode, dnode, flags, trn);
	//return true;

((ToggleVisibilityC* )dest)->switchFramesList.CopyFrom(switchFramesList);

That works, thank you very much!

the documentation includes the description of the BaseArray class (and its member functions like CopyFrom() ).

best wishes,
