VCAC/VCO integration - "workflow template"

Hi All,

One way to extend VCAC/VCO is by making VCAC call VCO workflows during state change. You make a copy of "Workflow template" and do other integration so that it gets called by the blueprint. The question is the "Workflow Template" has number of input parameters vCACVm, vCenterVM etc. How these are getting set by VCAC as nothing was done by me on the blueprint.

Any help appreciated.
