Parameter conversion not allowed - MQL5 - CArrayObj - c++

Question

I have the following object declared in my global scope:
CArrayObj *UpwardMovements = new CArrayObj;
And I want to add CUpwards objects to UpwardMovements. CUpwards inherits from CObject so it is possible to add it to the array. However, I cannot add it to the array in a method.
For instance:
void OnTick()
{
CUpwards *UpMovm = new CUpwards(ColorForUpwards);
UpwardMovements.Clear();
CalcUpwardMovement(UpMovm);
}
void CalcUpwardMovement(CUpwards &pUpMovm)
{
UpwardMovements.Add(pUpMovm);
}
I get:
'pUpMovm' - parameter conversion not allowed
If I do the same in my OnTick() method, it works.
Any help would be greatly appreciated.

Answer 1

Using * vs reference. Last line of OnTick(), change to
CalcUpwardMovement(*UpMovm);
Because that method uses reference.

Weird ... does your compiler want another parenthesis? I'm just guessing. I think it should not need another parenthesis.
Your code, with my proposed fix (see "change here" comment)
void OnTick()
{
CUpwards *UpMovm = new CUpwards(ColorForUpwards);
UpwardMovements.Clear();
CalcUpwardMovement( (*UpMovm) ); // change here <<<<<<<<<<<<
}
void CalcUpwardMovement(CUpwards& pUpMovm)
{
UpwardMovements.Add(pUpMovm);
}
Perhaps you did not mean to use the reference (I see you named the formal parameter 'pUpMovm', but a reference is not a pointer. Did you change your mind one place but not the other?
Perhaps you want UpwardMovements.Add(pUpMovm) to be able to modify the local variable pointer UpMovm in OnTick() ... but in this code that would be pointless as the modified pointer would not be used.

Answer 2

I solved the problem as follows:
UpwardMovements.Add(GetPointer(pUpMovm));
You may want to check the pointer before this operation with CheckPointer(GetPointer(pUpMovm));
