Cannot serialize object

[ShiroDoMain]

Hi! This is an awsome project! However, when I tried to use vtklocal on my project, there was a problem, the program kept outputting that the vtkSliderRepresentation2D object could not be serialized.

Yes most widgets are not supported yet. The one you mentioned is already captured here. That specific widget is not that useful with trame since you can make it in 2D very easily. So that one may not happen any time soon. But we are working on other widgets.

Closing since it is already capture in another issue.
