Detailed documentation on Input Parameters Presentation Tab

This post was originally published on this site

I’ve created a workflow using the Infoblox IPAM Driver for VMware vRA / vRO.  The workflow uses vRO Configurations and Extensible Attributes in Infoblox NIOS to find a list and return a list of hosts.


But in trying to get the Input Parameters to be more dynamic, I’d like the final confirmation screen to show the specific selected hostname from previous tab drop down list and the text input valid hostname (which I would like to be validated non-existent hostname).  I’m having a hard time finding good documentation and examples for presentation.  VMware documentation from

Doesn’t give detailed information on what presentation property type provides.  Here’s what I have so far:

The ${hostName} only shows the top value of the list and not what is selected, and ${SingleAliasRef} shows “Not Set.”


Any help or direction would be much appreciated.
