Railing Types node duplicate outputs bug

Hello!

I’m having a strange problem that is very simple to explain, but (apparently) very difficult to debug.

I create a new dynamo graph and place the OOTB node “Rail types”. I save the file. I open the same file and suddenly the node has two outputs instead of one. Every time I save and open it again, there is a new output:

Railing Types issue

This messes up the graphic and from then on I can’t use it.
Has this happened to anyone?
Any suggestions to solve this?

Thanks !

This occurs when you have a conflict with a dependency between Dynamo and Revit or one of the packages which Dynamo loads.

Troubleshooting steps:

  1. Make sure you have completely updated Revit.
  2. Make sure the Dynamo packages you’re using are the correct ones for your Dynamo and Revit version.
  3. If after those two steps it persists, then disable ALL your Revit add-ins and see if it that clears up the issue.
    • If so:
      • Add the Revit add-ins back in small groups until you find which one is causing the issue. Note that a binary search can help reduce the number of tests here which is good as you will need to restart Revit at each test.
      • Once you know which add-in it is, either: leave it disabled, update to the latest build, or inform the provider of the conflict.
    • If not:
      • Be sure that you have all Revit add-ins disabled. 99% of the situations where this continues my colleagues have found that something was left enabled.
      • Next step is to reach out to my colleagues in support, by submitting a ticket at manage.autodesk.com. Be sure to attach your Dynamo log and Revit journal to the case as that will be the first request.

Hi @jacob.small , thank you for the reply.

I’ve been trying to debug this, specially regarding packages and plug-ins and sadly couldn’t solve it. I found a workaround with the data-shapes package, by providing the railing types list as an input.

Thanks anyway!
