---------------------------------------
Summary: PState.changedVariablesStack not being maintained by VRef
in DPath expressions
Key: DAFFODIL-2565
URL: https://issues.apache.org/jira/browse/DAFFODIL-2565
Project: Daffodil
Issue Type: Bug
Components: Back End
Affects Versions: 3.1.0
Reporter: Mike Beckerle
By inspection found that while PState.setVariable was maintaining the
changedVariableStack, other places that read variables were not.
Specifically, in DPath expression evaluation, VRef is not.
We should do all variable sets/gets from PState/UState so as to always maintain
this stack properly.
