vCO endpoint, vCAC CDK exception

Hello, I've configured a vCO endpoint and Visual Studio/vCAC CDK per Tom's article: http://clearascloud.blogspot.com/2013/03/vmware-vco-workflows-integration-with.html (cross posted, will update once a solution is found)

I get an exception when trying to select the vCO workflow in the InvokeVCOWorkflow activity within Visual Studio (2010 SP1): vCO endpoint priority is not configured correctly. The vCO server is using LDAP (tested logon), and the endpoint is configured with the VMware.VCenterOrchestrator.Priority set to 1 (in fact it doesn't let you save the endpoint without this property set).

Any ideas?

Thanks,

David
