New Script Components Incompatibility Issues in User Object

Scripting
,
1

It looks like when I make a user object using the new script component, it only works in the same version.
In a different version, users are running into one of these error:

  1. Rhino version older than mine:
    The User Object could not be created as the base type is missing.
  2. Rhino version higher than mine:
    User Object failed to deserialize.

When I open a file with a different version of the script component, it’s automatically updated to the current version as I expected. But, this doesn’t seem to happen for user objects.

Hi Mahdiary. How old is the user object? Would you mind sharing one with me that throws error in 8.3 RC?

Hi Ehsan.
I only have a user object I created six months ago with the Rhino WIP. Unfortunately, I’ve deleted the other files that were not working. I’m also attaching the file I used to make this user object. It’s odd, the file opens without issues, but the user object itself isn’t functioning properly. It appears on the Grasshopper canvas toolbar, but when I use it in a document, it triggers an error.

Actually, I’m not completely certain if this problem is due to version differences. Sometimes, I encounter the same error even with user objects created using the same Rhino version. Nonetheless, I’m trying to replicate this issue. If I can, I’ll send over the file for a closer look.

Ok great catch and thanks for the .ghuser example. Solved and will be in the next 8.3 RC

@Mahdiyar Did you happen to get the today’s 8.3 RC build? I see you marked my previous message as Solution so I’m assuming the fix is confirmed?

I have just downloaded and tested the latest RC build, and there are many improvements. Thanks.
I can confirm that the user object from the previous service release works with this one. However, the older user object that I sent you earlier is still not working; it continues to trigger the same error as before.
