getCustomFiled failing after upgrade to 5.5

Hi,

After upgrading Orchestrator to 5.5 I can no longer run the "getCustomField" action (nor the "Get Custom Attribute" workflow which calls that Action) successfully. I am getting the following error:

TypeError: Cannot read property "length" from undefined (Dynamic Script Module name : getCustomField#11)

After a short investigation it seems like VcVirtualMachine.vimHost.customFieldsManager.field is returning null (i.e., no custom attribute definitions are returned in the field array). If I browse through the mob tree for the same vCenter I can see the customFieldDef array without problems.

The vCenter is still at 5.1 and the vCO is now 5.5 and so is the vCenter plug-in.

Is anyone else seeing this?

Cheers,

Milos
