Exception calling businesscalendar function
SA-7850
Summary
While executing DefineSLATimes(Pega-ProCom:06-01-01) activity, an exception is encountered in step 7 where we call function addTime(Lib(Pega-RULES:BusinessCalendar).).
This function will call checkCalendarCache function, which tryes to load calendar from DataBaseImpl, so it starts an authorized process which fails with next message:
"ERROR Trying to save an invalid page: ** Flow PreliminarySession had an error in step ASSIGNMENT52:
com.pega.pegarules.pub.runtime.IndeterminateConditionalException: Trying to evaluate Rule-Access-When conditions IsSystemRequestor when there is no page to evaluate them against Trying to save an invalid page: page is not valid"
From other places, isSystemRequestor is called several times, all of which work properly.
In this case, all these actions are performed by an agent.
When the activities and other rules are executed under a normal user, everything works fine.

Trying to save an invalid page: page is not valid
Steps to Reproduce
You have a timer which will wait some times.
After the time is up, the agent starts an activity and calls performFlowAction.
The Flow goes to perform an assignment with defined service level.
Root Cause
An attempt was made to call a a Business Calendar function from Agent processing.
By design, agents do not run with calendars.
As a result, no business calendar is available and an attempt to reference a calendar page is invalid.
Resolution
A different technique to calculate the desired time/date frames will be devised.
