I thought for "pick" you have to use GetAddPick() method?

The methods with "pick" in the name, pick the argument that you pass the method. But in your first example you use the assignment operator which "picks" the value from the right to the left variable.

I think you want something like this:

#include <Core/Core.h>

using namespace Upp;

class mycontainer: Moveable<mycontainer> {
public:
	VectorMap<String, String> data;
};

VectorMap<String, mycontainer> vm;

CONSOLE_APP_MAIN
{
	mycontainer &ca = vm.GetAdd("First");
	ca.data.FindPut("first-first", "aa");
	ca.data.FindPut("first-second", "bb");
	
	mycontainer &cb = vm.GetAdd("First");
	cb.data.FindPut("first-first", "cc"); // run-time error
	cb.data.FindPut("first-second", "dd");
}

Like that you don't call the assignment operator but you just use the reference that get's returned from GetAdd. So there is no picking.
