Getting Parameter Values of Linked Elements

Hi all, I’m using Bimorph Nodes to handle elements from a linked model, but when trying to retrieve parameter values, I’m being faced with the following issue. It works for native parameters, such as Mark, but not for the shared parameters. Any ideas?

I’m now employing a clumsy workaround: use the Element.Parameters node to retrieve all the information, convert to string and use a filter to find the parameter I’m after. Not elegant.
