Man... These types are messing me up:
vdc is input type vCloud:AdminVDC
vdc.isEnabled = false;
actionResult = System.getModule("com.vmware.library.vCloud.operation.admin").updateAdminVdc(vdc);
TypeError: Cannot find function update in object DynamicWrapper (Instance) : [VclVdc]-[class com.vmware.vmo.plugin.vcloud.model.Vdc] -- VALUE : com.vmware.vmo.plugin.vcloud.model.Vdc@271f957d. (Dynamic Script Module name : updateAdminVdc#1)
