Unlink and Relink ExportName after every run

I am using the Data-Shapes package Export to FBX. It runs perfectly the first time, but if I need to run it again, I have to open the file and unlink the ExportNames string and reconnect it. It returns Null if I don’t do that, and I don’t get any file exported. Does anyone have any idea what is causing this? Or is there another similar package out there that can export a view to FBX?

Use Dynamo Player.

Using Dynamo Player does the same thing. It won’t seem to export unless I go in and unlink the ExportNames parameter and reconnect it.

can you do a gif showing how your currently doing.

I’m not sure how to create a gif from it, but here is a quick screencast I just recorded. You can see when I try to run it, the export returns Null, and nothing exports. If I disconnect the node, run it, then reconnect the node and run it, it exports fine.
