How severely does this bug affect you?: 

●●○○ — It's annoying but I can work around it.

Steps causing the bug to occur: 

  1. I created a composition exactly as the same as the page 80 of the pdf user manual
  2. selected the 4 nodes in tangerine color (make sphere, trim 3d object, show back of 3d object, transfom 3d object)
  3. right-click and select "package as subcomposition"
  4. save the subcomposition
  5. execute the main composition and an error message occurs : Couldn't get backing node class. — 'vjdobermann.makeSphere.VuoInteger' uses generic types, but it couldn't be compiled. Check the macOS Console for details.

Have you found a workaround?: 

don't use subcompositions

Thanks so much for that

Thanks so much for that additional information. We wonder if the compiler is incorrectly detecting that .vuo subcomposition in a way that would create an errant .c file.

Could you try removing the vjdobermann.makesphere.vuo file, and try emptying the User/System Vuo Modules folders, too? If you can send us the unloadable subcomposition, it might help us reproduce and fix the problem.

Thanks for forwarding the

Thanks for forwarding the files! We were able to figure out the problem, which is a published, unspecialized generic port in a subcomposition. I've modified the title of your bug report to reflect that.

The workaround:

  • Open vjdobermann.makesphere.vuo
  • Delete the Material published port.
  • Right-click on the Material input port. Under Set Data Type, select any option other than Generic.
  • Re-publish the Material port.
  • In testing 8.vuo, replace the subcomposition node (now marked as "not installed") with its new version from the node library.
