View from new row loses attachment

When getting a view from a new (unattached) row, it seems to loose it's connection with the row. If this is not a bug, it does at least seem counterintuitive and is different behaviour from when you get a view from an attached row.

The following code shows the problem:

    #include "mk4.h"
    #include <iostream>
    using namespace std;
    void main() {
        c4_ViewProp pView("view");
        c4_IntProp pInt("int");
        // Create a row containing an int (for comparison)
        // and a single view
        c4_Row r;
        c4_IntRef i1 = pInt(r);
        c4_View v1 = pView(r);
        // Set the int and add a row to the view
        i1 = 99;
        v1.Add(pInt[99]);
        int value1 = pInt(v1[0]);
        cout << "v1: int=" << (int)i1 << " rows=" << v1.GetSize() << " value=" << value1 << endl;
        // Try to retrieve the int in the view through the original row
        c4_View v2 = pView(r);
        int value2 = pInt(v2[0]);
        cout << "v2: int=" << (int)i1 << " rows=" << v2.GetSize() << " value=" << value2 << endl;
    }

On my system it gives the following output:

  v1: int=99 rows=1 value=99
  v2: int=99 rows=0 value=0

Summary

Attached vs. unattached view issues are due to flaws in the design of Metakit. These cannot easily be fixed.
