Visualisation breaks after a package update

[MikeInnes]

Updating the manifest breaks the Trebuchet example. There's a WebIO upgrade involved so it could just be a WebIO/Juno incompatibility, but it might be worth investigating.

Edit: Pinning [email protected] is indeed enough to fix this.

[carstenbauer]

Pinning does fix this in IJulia as well (the visualization shows up), but below the animation I get

KERNEL EXCEPTION
KeyError: key "data" not found

which, however, doesn't seem to have any effect.

I just spend 2 hours on this problem that nothing seems to work on current packages...

I am glad I found this issue now to be sure, that it is neither Firefox, nor Chrome, nor Julia version, nor whatever. It is just an incompatibility between Trebuchet and WebIO...

Please, consider taking the time and updating this example. I was trying to do a small demo for Flux.jl using Trebuchet.jl, however given it is not working on current packages, I cannot really present it... It is really a pity, especially seeing that this issue is already about a year old...

Even worse, trying to install [email protected] is not possible due to incompatibility:

(@v1.4) pkg> add [email protected]

The example given in the README seems to work on Julia 1.4.1 with these package versions:

(@v1.4) pkg> st
Status `~/.julia/environments/v1.4/Project.toml`
  [c52e3926] Atom v0.12.14
  [ad839575] Blink v0.12.3
  [e5e0dc1b] Juno v0.8.2
  [98b73d46] Trebuchet v0.1.0 [`~/.julia/dev/Trebuchet`]

[schlichtanders]

any plans to make this compatible with the current WebIO version?

[Roboneet]

Made an update. Can you try master?

[schlichtanders]

@Roboneet thank you very much for trying to fix this. It works almost.

I can see a visualization, however if I do a second visualization in a jupyter notebook right below, only the visualization part works, but not the update of the Distance/Height/Time text fields respectively.

What happens is that the Distance/Height/Time fields from the very first visualization get updated instead.

Here a screenshot, as I don't how to create a gif quickly (I wrote my own wrapper function to actually trigger visualization, nothing of importance to this issue)

[Roboneet]

Thanks for bringing that to notice. I've fixed it

[schlichtanders]

I can confirm, it works now for me! Really great. Thank you for very much for you efforts!

Are you going to do a new release?

[Roboneet]

Yeah, I could make one
