Cannot see inventory with Director 1.5 plug-in.

vCloud Director 1.5.1.622844

vShield Manager 5.0-473791

Orchestrator 4.2.1

Director Plug-in 1.5

ESX 5.0

When working with workflows from the vCenter library, I can expand/surf the inventory hierarchy. But when I use the vCloud Director workflows, I can't expand the inventory. The issue has been replicated in a test lab in addition to my build. Has anybody else experienced this?

Thanks!
