[Juan Fernandez]

fxsaber:
Give an example of what you mean?

template <typename T > A {

T data[];

} 

new A< MqlRates >();

Juan Fernandez:

template <typename T > A {

T data[];

} 

new A< MqlRates >();

template <typename T>
class CLASS
{
  T Data[];
};

void OnStart()
{
  CLASS<MqlRates> Object;
  
  CLASS<MqlRates>* Ptr = new CLASS<MqlRates>;
}

fxsaber:

Sorry. You are right. Its failing ArrayCopy inside my wrapped classes. I confused because classes with error are using structures in template parameter

#property strict

struct STRUCT { string l; };

void OnStart()
{
  STRUCT Array1[], Array2[];
  
  ArrayCopy(Array1, Array2); // 'Array2' - structures containing objects are not allowed
}

[William Roeder]

struct STRUCT { string l;       // object
   void STRUCT(void) : l(""){}  // default ctor
};

void OnStart()
{
  STRUCT Array1[], Array2[];
  
  ArrayCopy(Array1, Array2); // structures containing objects must have a default constructor
}
