378	Error using Estimate	Christian Paz	Víctor de Buen Remiro	"This is an error a little difficult to reproduce, this model is totally
senseless but serves to illustrate the error, that I suppose is unrelated to the
model definition.

In the Estimate call, an error related to Unknown structure for field :

-> ERROR: [1] Attempt to access to field Function for an unstructured set

I am sorry because I cannot isolate the problem more, I hope this helps, I am
going to try isolate it more.

Thanks,
