Query table in GVH

I thought I'd seen a post or documentation on this topic but couldn't find one when I looked.

I've got a workflow on an old GVS that searches records on a feature table published through a map service that's been added to my site. The basic process is to

1. use Get Map Service Info to get the URL and layer ID for the feature table
2. use a Display Form to ask the user to select a record from the table using an Autocomplete box
3. use the selected record to open a file of the same name that exists in a file folder on my web server

I can see with debug setting on Get Map Service Info that it's failing to get the layer ID of the feature table, which I need in order to use the table values in a Display Form. Is this expected behavior in the GVH?

Version info:

• The workflow works in GE 4.1 with the GVS 2.2
• It's not working in GE 4.3 with the GVH 2.4
