vCAC plug-in, unable to access properties via vCACEntity.getProperties()

[dcoulter]

Per the vCAC plug-in documentation I'm able to retrieve vCAC entities:

http://pubs.vmware.com/orchestrator-plugins/index.jsp?topic=/com.vmware.using.vcac.plugin.doc_51/GUI...

var modelName = 'ManagementModelEntities.svc';

var entitySetName = 'VirtualMachines';

var headers = null;

var properties = {};

//Read a list of entities

var entities = vCACEntityManager.readModelEntitiesByCustomFilter(vcacHost.id, modelName, entitySetName, properties, headers);

System.log(entities[0]);

produces:

However, if I attempt to access the properties (via entity[0].getProperties() or entity[0].getProperty('VirtualMachineName'), I get a java.lang.NullPointerException.

I am also seeing the same issue.  Plug-In Version vCAC 5.1.0.197

Looks like while adding properties to map is failing with null pointer exception. If the key or value is null then we will get this, probably if any of the VirtualMachine attribute have null value then this might happen. Just a null check missing in the plug-in?....Appreciate for any clarifications.

Please try with this plug-in :

https://communities.vmware.com/docs/DOC-24278

I remember having the same issue you have and submitted a bug that was fixed in the link above.

Thank you. Will give a try.
