vCloud:GuestOSType - VclGuestOSType()

Hi all, how do I set a value for vCloud:GuestOSType ?

I can read all the values, but how can I set the variable so I can create a VM.

I have a Workflow that has vcloud:GuestOSType as input variable. The customer is passing me a string with his PXE image and I need to phrase it to determine what OS he wants.

So I have ATM an Action that has as return a type vcloud:GuestOSType

var myVclGuestOSType = new VclGuestOSType() ;

it allready errors on the VAR with

[2013-08-01 16:33:54.780] [I] Unable to create object : _VclGuestOSType : com.vmware.vmo.plugin.vcloud.model.enumerations.GuestOSType

So Not sure how to do it.
