CopyFieldHint \ MoveFieldHint does not work when reference field is moved in hierarchy #754

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The case is:

Old model:

class X {
}

class A {
}

class B : A {
  X Reference;
}

New model:

class X {
}

class A {
  X Reference;
}

class B : A {
}

Attempt to apply proper copy\move field hint leads to this error:

“Sequence contains no matching element”

The possible reason of this error is incorrect upgrade hint. For example 
incorrect original class (or field) name. Class name must contains namespace.

Upgrade was modified to throw exception with detailed description for such 
cases.
