Scriptrunner in Automation for Jira - No such property: ruleContext for class: <script_name{

[Ariel L. Dor]

Hi,

I've tried to load a file containing a common class through 

def utils = new GroovyScriptEngine( '/var/atlassian/application-data/jira/scripts/com/mprv/automations/EscalationSLA' ).with { loadScriptByName( 'EscalationSLA_utils.groovy' ) }
this.metaClass.mixin utils

Now, this sub-script contains calls to ruleContext:

String smartValue(value) { return ruleContext.renderSmartValues(value) }

(yes, I'm lazy - don't judge...)

however getting the error

com/mprv/automations/EscalationSLA/EscalationSLA_IssueTransition.groovy, error: groovy.lang.MissingPropertyException: No such property: ruleContext for class: EscalationSLA_IssueTransition
groovy.lang.MissingPropertyException: No such property: ruleContext for class: EscalationSLA_IssueTransition
	at Utils.smartValue(EscalationSLA_utils.groovy:18)
	at EscalationSLA_IssueTransition.run(EscalationSLA_IssueTransition.groovy:50)

Seemingly, the rule context is not passed to the runtime of the second file - is this even possible?
