Set Description on VM from VRO

For the life of me I cannot figure out how to set the virtual machine description from vro.

I'm passing in the VCAC:VirtualMachine and doing a getEntity() on the object to get the entity.

Then I output the properties and see: Notes=Provisioned by VMware vCAC

Then I pass the virtualmachine entity to "Create / update property on virtualMachine Entity" with property name "Notes".

The flow says that it's added a property Notes on the first run.  On the second it says it has updated the property.

When lookign at the properties on entity.getProperties()  Notes is still listed as the old value and there are no new properties.

What am I doing wrong here?

Thanks!
