Querying shader that has pending params

[john2034j]

Heya, I'm trying to query an application that is setting up some pending parameters before creating a new shader in a shader group.

The problem is when I query the shader group and look at the values of the shader parameters, they are the same as the default values.
Is it possible to get these values out of the shader through an OSLQuery, or is the shader in the query not the ShaderInstance I want to get?
