Is ScriptRunner's originalIssue valid in workflow transition's Post-function?

Question

Before banging my head much further, I have a question:

Reading https://jamieechlin.atlassian.net/wiki/display/GRV/Built-In+Scripts#Built-InScripts-TechnicalStuffforAdvancedUsers, not sure if only available in validators.

I'm using scriptRunner to send an email in the post-function if the value of that custom text field changes. i.e.  the Condition:

def cf = customFieldManager.getCustomFieldObjectByName('CSR#')
     val = issue.getCustomFieldValue(cf)
     oldVal = originalIssue.getCustomFieldValue(cf)
     val == oldVal

The email is being email every time whether the CSR# field is changed or not.  What have I done wrong this time.

C/Perl guy  ;-)

Reworked the workflow and made setting the CSR# field in a separate global transition which only a certain jira group can fired.  Problem solved for now until I run into the next problem that requires reindexing.  ;-)
