I believe I overthink things too much - someone (several someones actually) told me that before...

My solution to this issue is to override the Open function for each affected table/class thus:

void InvoicesWindow::Open(Ctrl* owner)
{
	InvoicesArray.ReQuery();
	InvoicesArray.GoBegin();
	
	TopWindow::Open(owner);
}

That way I don't need to expose extra access, pass pointers etc...

I haven't found any issues with this yet... Thanks all!
