JOC Cockpit GUI can freeze when a user with restricted permissions accesses Resources

Current Situation

Consider a user with the following permissions:

 sos:products:joc_cockpit:calendar:view:status
sos:prducts:joc_cockpit:jobscheduler_master:view:status

• After logging on the user accesses the Dashboard and is able to select the Resources menu link
• When the user selects the Resources menu link the page starts to load and then freezes. The JOC Cockpit cannot be used but the browser's own Back button still functions.

The same behaviour occurs when the user has the permissions:

• sos:products:joc_cockpit:calendar:view or
• sos:products:joc_cockpit:calendar

A Log file covering the steps described above is attached.
The last POST events does not contain a response.

Desired Behaviour

It should be possible for a user with the permissions listed above to access the Calendars tab.
