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

[Brent Webster]

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

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

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. ;-)

After more testing, I believe that once the transition's post-functions start to be evaluated, the originalIssue equals the issue object. So in a post-function, what is the best way to trigger a post-function email generation when a custom field is changed? Have a hidden text field saving the previous value?
