DataByQuerySpecRequest - Data Access Manager Library

Hi,

I am trying to use the DAM library to gather the list of VM's (and possibly other objects once I get this part for VM's working).  In reading the documentation, it looked to me like the DataByQuerySpecRequest is what I need to use.  Specifically, I was referencing the following document:

vSphere 5.5 Documentation Center 

This document section talks about the DataByQuerySpecRequest, but doesn't give specific examples for it, so I have sort of modeled my code after the similar methods which do have examples {DataByConstraintRequest}.

One thing I thought was odd is that the example uses the "QuerySpecUtil" which is only a sample class and not part of the real API.  At any rate, I reviewed the HostSampleSummarySectionViewMediator.as sample as well.  I was also able to find this reference document which does give an example for DataByQuerySpecRequest, but the example is filled with errors (sample link below):

API Documentation

I tried to follow this documentation as best as I could, but there is quite a bit of ambiguity, and I have not done something correctly.  I was hoping someone else can see what I might have missed or done incorrectly.

From my code, I have a primary mediator class.  This mediator class is calling my Data Manager Access class, which would/could use my Data Model class (DAMModel)...  but one big piece of the puzzle that I think I'm missing is, I don't know where to pass my Data Model.  But perhaps I don't need it when using the DataByQuerySpecRequest?  I just can't tell based on my interpretation of the docs.  I think I am making the request correctly, but I am not getting any response.  That is to say, nothing at all happens after I make the request... no success, no error, no exceptions, nothing.

Any help is appreciated, thanks in advance!
