vRO - NSX Plugin - NSX:PoolMember and groupingObjectId

During working on workflow for creating a server pool (and using the existing default wf), I've encountered a problem - it seems that while passing groupingObjectId of security group (objectId param.) it is not populated upon server pool creation - am I the only one or have anyone seen such behaviour?

As mentioned above I am using what was already provided by VMware so it goes something like this:

var poolMembers = new Array();

var poolMember = new NSXPoolMember();

poolMember.groupingObjectId = securityGroup.objectId;

I noticed that while using API calls apart from object id, it's name is also passed, here I can see no attribute for passing name. I wonder if that might be the issue.

Any comments appreciated.
